Did she explain more about how night feeding was affecting weight gain?
Apparently because she is feeding during the night, it's affecting her daytime appetite. Which, now that I think about it.... is just plain silly!!! She's not guzzling litres of milk every night! Most night she wakes once, and feeds for a maximum of half an hour.

I just didn't like being told that I am hindering my DD's growth and development!... DD is as sharp as a tack!
