Week 3
You may notice your baby will respond to loud noises. Though if repeated enough, he will learn to tune them out. You baby will respond to sounds by blinking, startling, frowning and waking from a light sleep. However, a sleeping baby need not mean a hushed household. Ordinary sounds and activities will not disturb him at this age. But, if everyone creeps about and speaks in whispers while the baby is sleeping, the time may come when he cannot sleep unless it is absolutely quiet. Therefore, it is important to let him sleep through whatever sound level is normal for your household.
If you are breastfeeding, it will have become more natural for both you and your baby. If not, then read some tips for starting out right. If you are experiencing breast pain, check with your doctor, for you may have a breast infection.
Some babies will begin to show signs of colic after their second week. If your baby has started crying, pulling his legs up towards his chest, for at least one hour, but often for 3 hours or more, he may have colic. Usually, a similar pattern repeats itself every day at about the same time, and is not seen at any other time of the day. Colic occurs in about 20% of babies -- the cause is unknown, however most pediatricians say that it is a result of an immature digestive system. Colic usually goes away by the 3rd month.
