Well, my 4 month old daughter is another snacker. She's exclusively breastfed and nurses about every hour for only 5 mins at a time. She is gaining wait perfectly and has regular diaper output. However, she does seem to spit up an awful lot.
I've read other posts about frequent nursers and agree that it's the best thing that I feed her on demand, regardless of how it may inconvenience me sometimes. My pediatrician also said that there is a wide range of "normal" in 4 month old eating habits and that it's not a big deal.
The only thing that really is bothersome is that she wakes up 3-4 times a night still and that makes for one tired mommy!!! She suggested that I could try supplementing her with some baby rice cereal once a day to try to keep her stomach a little fuller. But then she said that could just trick her and into thinking she's getting what she needs instead of actually fulfilling her needs. So I've been torn and was wondering if you had any input? Thanks
