At my daughter's 4 month check up a week ago, we found out she had gained only 2 oz. in a month's time. During the first 3 months she gained a little over a pound each month. She has been exclusively breastfeed, on demand, not on any schedule, sometimes every half hour, sometimes she'll go for 2 hours. Doc said he's not too concerned, said she's probably just snacking all the time. Suggested that I make her wait and nurse her every 2-3 hours, then she would be really hungry and nurse well. I'm not really comfortable with this. I think it might be more of a supply problem. She was a good napper and was sleeping through the night till about 2 weeks ago. Now when I nurse in the day, she falls asleep, but when I put her down she's back up in 5-10 minutes wanting to nurse again. There's also times in the day when she wants to nurse, but the milk just isn't there. Would feeding her more often increase my milk, even if she just snacks? Or would it be better to make her wait? This is my 3rd child, I've had supply problems in the past and ended up using formula. I REALLY don't want to supplement. Any advice?
