After birth, babies should be breast-fed or formula-fed. You do not need to give water to the baby. Baby may cry because of hungry, wet diaper, discomfort, or no reason at all.

For the first three months, avoid bringing the baby to public areas such as shopping malls. This prevents the baby from being infected by virus.

The development of a baby:

During the sixth week, baby starts to discover her hands and feet and realized that they are part of her body. She may also start to express herself with sounds other than crying.

During the eighth week, baby starts to have more control of her hands and feet. For example, she may start to grab for things. She may show that she is happy by cooing.

In week 13, your baby may be strong enough to do mini-pushups, lifting his head and chest and look around.

Starting week 14 until six-month old, babies are drawn to faces more than anything else. They like to look at their own faces in the mirror, or faces of family members.

In week 18, your baby may be able to roll over from her back onto her front and vice versa.

In week 19, she starts to discover the principle of cause and effect. She tries to get your attention by all means.

In week 20, you may be able to make your baby laugh by imitating his facial expression or sound. If you repeat the same word again and again, he may even start to make some recognizable noise, maybe "Ma-ma" or "Da-da."

To balance the development of your baby's both sides, alternate which side you breast- or bottle-feed on, and place her head at one end of the crib one night and at the opposite end the next night. Balanced movement leads to greater muscle control, which she'll need to master eye-hand coordination sometime around her ninth month.

Starting week 22, she may laugh at funny expressions and try to make you laugh, too. She's showing her emotional side in other areas, as well. At this age, she'll demonstrate her strong attachment to you by raising her arms when she wants you to pick her up, crying when you leave the room, and giving you hugs and kisses.

In week 24, he may start playing little games as he begins to understand cause and effect and the results of simple actions. He may drop objects just to watch you pick them up, or he may throw something to see where it lands.

Starting week 25, you can show her that other people can love her almost as much as you do. Let her spend some time getting accustomed to warm, trusted caregivers and babysitters. The experience will help her feel more secure a couple of months down the road.

In the seventh month, your baby will really learn to put his hands to good use. He'll quickly master the art of raking objects toward himself -- and he'll figure out how to move something from one hand to the other. And once he learns that he can hold something in each hand, he'll quickly realize how much fun it is to bang them together. He'll want to practice this new skill, so if you think you can stand the noise, set aside one kitchen drawer or cabinet and fill it with baby-safe pots and pans for him to play with.

Six-month-olds love turn-taking games, especially those that involve sounds and language. Let your baby go first, and mimic the sounds she makes. When it's your turn to lead, you can teach your child -- and make her laugh at the same time -- with animal noises and sounds like "baaa" or "maaa".

In the eighth month, baby starts to practice grabbing things. You can encourage his skills by placing a toy just out of his reach. After a few tries, she will be able to lean forward to grab it and then straighten herself again. Mentally, she will make a huge mental leap and finally understand that she is an individual, with her own body, thoughts, and feelings. At this age, a simple game of peekaboo will absolutely fascinate your baby. She is starting to understand object permanence (things don't go away forever when they leave her sight), and she loves games where people or things appear and disappear. In fact, one of the easiest ways to keep a 7-month-old occupied is by hiding an object under a blanket for her to discover. Also in this month, she may try feed herself. Help her, and forgive the mess.

Some kids walk as early as 7 months, others at 17 or 18. Most figure out how to walk pretty easily on their own. The thing that stumps many is sitting back down! When your little guy pulls himself to a stand and then cries for you to sit him back down, don't rush to his aid. Instead, show him how to bend his knees so his trip back down doesn't end with such a thud.Now that your baby is mobile, he can really indulge his fascination with toys and other interesting objects. Once he gets hold of something new, the experimenting begins. He'll shake, bang, drop, and throw it. And of course he'll put it in his mouth. He's also beginning to see how objects relate to each other. For example, he understands that smaller things fit inside bigger ones. Encourage his explorations with stacking cups and shape sorters. Blow your baby a kiss this week and she just might blow one back to you. If she does, encourage her with smiles and applause, and she'll probably offer more airborne kisses. Not only has she developed the physical coordination to make that tender gesture, but also her emotions are beginning to bloom. That's because she's starting to notice other people's moods. She may even cry empathetically if she hears another baby crying.

Nine-month old: Even if your baby is cruising, don't invest in baby shoes until he walks independently and can easily navigate rough or uneven surfaces. Experts say going barefoot in the beginning helps him develop his arches, leg muscles, balance, and coordination. Once he stops holding on and takes some initial wobbly steps without help, though, head for the shoe store -- your baby will probably progress amazingly fast (usually in a matter of days) from first steps to toddling more confidently on his own. Then he'll be ready to don shoes and try walking outside. Babies typically say their first words (often "mama" or "dada") sometime between 8 and 15 months. Even if she's not talking, though, she's probably amused by the sounds she makes and may express herself in other ways: by shouting for your attention, screaming in frustration, or dropping a toy just to watch it fall. Try diverting her with a game of peekaboo. She can play along now instead of just watching.

Ten-month old: Mealtimes are increasingly messy affairs. All this throwing isn't a sign of bad behavior, though. Many babies this age purposely drop objects for someone to pick up. By observing the reactions of people around him (mommy groans and stoops to pick up the cup) your baby is learning about cause and effect and discovering his own influence on the world around him. As babies begin to pay more attention to what's going on around them, it's not unusual for them to develop new fears. In fact, it's a normal developmental stage. Your baby may suddenly cry and cling to you upon hearing even familiar sounds such as the dog barking next door or the doorbell ringing. Your job is to provide lots of hugs and kisses.Words or wordlike sounds are now spilling out of your baby. When he chatters at you, just chatter right back, keeping your language simple -- but use real words, not baby talk. The idea at this age is to model the correct pronunciation, not to "correct" him. When he says "bah-bah" for bottle, for instance, say, "Yes, that is your bot-tle." He probably understands a lot more than you realize, so keep up your side of the conversation by describing daily activities as you do them, reading to him, and singing songs. the good news: Right about now your baby is probably perfecting the thumb-and-finger pincer grasp, an essential element of her developing eye-hand coordination. The bad news: You'll have to be extra careful not to leave small things that she could choke on lying around the house. She'll want to use her mouth to explore every fascinating little item within reach, from buttons to beans -- and her reach is expanding with each passing week. This makes baby-proofing a top priority, but don't hover too much; give her a chance to explore and practice her new skills.

11-month old: Ask your baby "Where is your mouth?" and chances are he'll touch his own. Most 11-month-olds can respond to simple questions by pointing to the named object. Your baby can also follow simple instructions: Tell him you want a kiss and he might just give you one. Many can babble in short sentences that sound like a foreign language, too. Keep talking to your child, naming and labeling objects and people. The more you do, the faster his vocabulary will grow.
