Is your baby puking a lot? By a lot, I mean like it seems most of the milk seems to come out after feeding. If your baby screams a lot right after feeding and pulls away a lot during feeding than it may be colic. But your baby would be crying every time after feeding. You should check with your pediatrician. True they don’t sleep through a whole night but your baby shouldn’t be crying throughout the night if it’s dry and fed. If your breast feeding, make sure your baby is getting enough to drink.
Could also be your baby misses you. My daughter was good baby during the nights early on unless I wasn’t near. So we placed the bassinet in the room and I would put my pj next to her for comfort. You can also try putting the crib next to the bed and put your hand next to her.
My sister-in-law use to have a crib that opened on the side so the baby could sleep next to you with a low boarder separating you. But I think the pj idea is best because it can be harder for your child to sleep alone later. I kept her in the bassinet for 3 months and then moved her to her own room and into the crib gradually. By then she was sleeping comfortably thoughout the night.
If your baby is crying and you know she is fed and dry and she isn’t colicky, then go into her room without turning on any lights and lightly pat her without picking her up. Sometimes people think the baby is fully awake when they may simply be having bad dreams or feel hot or some discomfort. Sometimes a gentle patting till they fall back to sleep is all they need to chase the dreams away and make them feel secure enough to fall back into a deep sleep.
It may take quite a few minutes the first few days and repeat action several times during the night, but eventually she won’t need it. Same thing with feeding during the night. Worse thing people do is turn on all the lights and pick up the baby, unless you are feeding. Even then pick up but don’t turn on the lights. Babies don’t know the difference between night and day. Lights in the room will make them wake up. She needs to get use to the idea that lights out means sleep time. Also try to keep her up longer between feeding during the day. She may be sleeping more than she needs during the day.
As she gets use to sleeping longer stretches during the night, you can start to stretch out her feedings during the night. Don’t worry. She will just drink a lot more during the morning and eventually drink more at all her day feedings. She won’t starve and you want her to increase the amount she drinks, and not the amount of times she drinks.
But do check with your pediatrician. Two week old babies can’t tell you what is wrong. Make sure she is fit all around. And if your baby is colic, that is nothing to be overly concerned. Your baby will out grow that. My son was colicky for 3 months. I know breast milk is the best but I’ve heard (don’t know if this is true) that you may need to avoid certain foods. I would think if you have a lot of coffee, soda or chocolate, that you are pumping your kid with caffeine.
