3-4 oz is just fine. he is only 9 weeks old. Some dr's are just crazy I think. :)

uhm, there's an equation-- if he's say 9lbs, times by 2--that's 18 oz a divide by number of feedings---HOWEVER. 3 to 4oz sound about right to me, and aslong as she keeps gaining weight---she's a "thriving" baby (ie. not lethargic, cries non-stop etc.) your sister shouldn't have to worry!!! (;

i wouldnt worry, my son is almost four months and still only drinks 4 oz at a time, (but like every 2 hours during the day) we're just starting to get him to drink 6 oz at a time. Every baby is different!

my 8 week old only eats about 3-4oz at a time and she's putting on weight pretty good. Our pediatrician says most babies her age eat between 4-6 oz every 3 or 4 hours. I don't worry about it as long as she's putting on weight. I feed her when she's hungry. She weighed 6lb 5oz at birth and is now 9lb. 14oz.

I agree with everyone. My ds is 9 weeks today, and if I give him b___stmilk in a bottle, he drinks about 4 oz. I tried giving him 5 oz this morning, and he spit a bunch of it up, so I a__sume his little tummy isn't ready for that much yet.

The rule of thumb is that for every pound your baby weighs he should take 2.5oz. So if he weighs 10 lbs he should be eating about 25oz in a 24hr. period. But every baby is different, and you can't put textbook to all babies, so it's just a rule of thumb, so take it as you want. My ds is 12wks and still only drinks 4oz at a time usually. So some babies make up their own rules. As long as he's got lots of wet diapers and gaining weight, he's fine. Good luck

My ds is 7 weeks and I bf. I have pumped and given him a bottle and the most he will drink is 3.5 oz. He still nurses every 2 hours and has gone from 9lbs 2oz at birth to 16lbs in 7 weeks. No that was not a typo...16 lbs! lol
