my dd was born nearly 8 weeks early and is now 3 1/2 weeks old. she is a great feeder and despite her low weight (4lb 14 1/2oz) she is taking between 80 and 90 mls during each feed. she goes from 4 - 5 1/2 hrs between feeds. when she was in SCBU they worked out that she should be taking 180ml per kilo per 24 hrs which would mean that she should now be having just over 360 mls per day. she is taking well above this (yesterday 435ml and today 340mls with another feed to go before midnight).
ideally she should be having 64mls every 4 hours based on her weight but i have tried to wake her after 4 hours by changing her nappy then giving her a bottle but she will not take it. when she is allowed to have it when she is hungry she will take 80-90mls.
is this a problem? my mother and mother in law say its fine as she is having enough out of 5 bottles instead of 6.
