ah mummatron my dd is like that at times, only wants 2-3oz at a feed, generally she now takes 4oz a feed, sometimes as much as 5oz, she is having 20-25oz a day but only wants to feed four hourly in the day and then goes two 5 hour stretches at night, i cannot get her to feed more, she just isnt interested, doesnt seem to be a hungry baby, yet is gaining weight well!
tbh i am more than happy with dds sleep, 7pm-11:30pm, feed and then through till 5amish, feed and then back to sleep till anytime between 7-9am :)
my first three were terrible sleepers, ds1 didnt sleep through till 3yrs, ds2 was better, but in our bed till 2 and a bit years and bfed at bedtime and morning till nearly 4yrs old! ds3 was sort of inbetween, not as good as ds2 but not as bad as ds1!
then we had ds4 who was a revelation that babies CAN sleep, from a young age he slept well, he sucks his thumb tho and i am sure that has a lot to do with it, bizarelly tho we have had problems with him now at just 3yrs as he is having nightmares etc, so he is regularly waking up when dd is asleep!! gahh
still they do all sleep eventually! my eldest is 11 now and from being a baby/toddler who liked to start the day at 5am! we now struggle to get him out of bed!
its all swings and roundabouts.
