i know babies get more efficient feeders as they get a bit older, but DS's 1st feed of the day was 5 mins at 9am (last fed 3am-ish), then 12pm had 5 mins. then at 3.30pm had 35 mins!!! - what's going on??? he usually has a steady 20 mins or so, although on odd occaisions has a much shorter or longer feed. Is he getting enough? are these shorter feeds normal?- am esp. worried as trying to cut down number of night feeds and am thinking oh no, what if he's not had enough today and wakes even more tonight?
