Sleeping on stomach

If you are holding her, then it's ok. The reason the APA suggests that babies sleep on their back is simply because if they get into a corner with bumpers (NO BUMPERS IN CRIBS :) or if she rolls onto her face she doesn't have the muscles to lift her head and she can suffocate herself. Congrats on your little girl and hang in there - you will be able to sleep again someday!

Here is one of the campaigns called "Back to Sleep" where you can get a little more info:

Jodi is right 100%.
Basically 3 weeks old is too young to sleep on tummy unless someone is holding her. SIDS is the problem like Jodi explained when it comes to tummy sleeping. Not only crib bumpers, but they tend to lose their breath or "smother themselves" when on their tummy.
But - when your baby starts rolling over on their own (4-6 months usually) and you know they can go from tummy to back (usually the first rollover anyway) without a problem, then you can relax a bit. Basically if they roll on/off their tummy while sleeping, don't freak and wake them up. lol. I was doing that and my pediatrition laughed. Once they can roll over on their own then they are usually okay (still no bumpers), but not at 3 weeks.

I have four kids and i let them all sleep on my stomach on there stomachs . I think its all right you just have to make sure that you and the baby don't roll over and the baby falls or you roll over on the baby. And as the baby get older he/she will roll and sleep how they are comfortable on their own.

Just wondering which is the best and closest bottle nipple to breastfeeding...I'm not sure which one to get -

Babies will have their own preferences which I discovered after buying a full-blown kit from medela. She hated them and wouldn't use them :)

So you should buy one bottle of a couple different brands and see what she likes. As far as for breastfeeding, the nipple isn't AS important as making sure that you have slow-flow nipples, so she still has to work to get milk from the nipple. If you make that too easy on them, they won't want to do the work involved in breastfeeding :)

I have recently converted my 10-month-old to the Playtex bottles with the disposable linings and swore on my life to recycle forever for the amount of liners and diapers I use, but it saves me so much time no having to wash bottles! I hated that!

How safe is the hepatitis b shot for infants and is there anything i should give her (tylenol) beffore getting the shot?

If your baby is due for the shot and your doctor recomends it - get it! My baby got hep b shot and didn't have any probs. There is a lot of controvesy over vacinations, but I personally would rather take the small (I think it's like 5%) chance of a prob w/ the shot than risk a high chance of him getting sick. Thats just me though.
Don't give any type of medication before the shot. Try to avoid it afterwards too. They have found that the shots are less affective if the child is given tylenol (or advil). If they get a fever they need to keep it (as long as it doesn't get dangerous - like above 101). It's the body's natural way to form a defence. It sucks making them cry, not having any way to calm them or stop the pain, but it needs to be done.
Talk to your pediatrition before they give the shot and see if you can give baby a little sugar water (in bottle). It distracts/calms some babies, but not all. I tried it with mine when he was 3 months, but it didn't make a big difference.

Enjoy it! The sound of your heart beat actually sooths her. I just wouldn't let it go past 3 months. She will end up getting use to it and then she won't go to sleep on her own. I did it for both my girls and it helped them as well as helped me to bond with my babies. CONGRATS!

I have 5 children and I have put all of them to sleep on their belly. That is the only way they would sleep and they are all ok. (ages 23, 21, 18, 16 and 4 plus I have 2 steps that are 18 &16 ). I think you need to do what is best for your owe child. The "higher ups" have to come up with something new everyday, we should all be dead by now, do you know how many raw hotdogs we have eaten in our life, not to mention, real butter, eggs, the lead paint cribs we slept in on our bellies, and the cars without seat belts in them! I could go on.....but, just do what you are comfortable with.

When you heat up breast milk and the baby does not drink all of it -- can you keep it for later use? and if so,, how long can you keep it for and where should it be stored?
