My son is 11 weeks old and exclusively breastfed. I've been back at work for 3 weeks so he gets a lot of bottles now. Two weeks ago, he went to the pediatrician and he weighed 11 lbs (30th percentile for weight, 70th for height).
I had read that babies should eat approximately 2.5 oz of milk per pound of body weight in a 24 hour period. So, figuring that he's probably slightly over 12 lbs. now, that would be 30 oz/day.
A couple weeks ago, he started sleeping more (up to 11 hrs a stretch) and so sometimes we only got 5 feeds in per day (every 3 hours during the day). Based on this, we started giving him 6 oz bottles when he bottle fed.
But now in the past week, he's started sleeping a little less, so has been getting in 6 feeds most days. Obviously I don't know how much he eats when he breastfeeds directly, but I would estimate he's been getting 36 oz/day for the past week. We haven't reduced his bottles because I keep hoping that he'll go back to sleeping longer at night.
Then I found this post this morning

where people say a breastfed baby should have a max of 30-32 oz a day, and never more than 4 oz at once.
It kind of freaked me out, even though my son is still very thin. Is it bad to give him 6 oz bottles? I haven't wanted to cut back on food because I keep hoping he'll go back to sleeping 10-11 hour stretches at night.
