Thanks Dansta for the feedback. Visited the Maternal Health Nurse yesterday, he has gone from just under 6lb when born to 8lb 3!!! He is a month old and she is telling me he should only be having 600mls of formula a day. I'm confused as the Karicare can has a rough guide and it works out to be about 900mls if following the guide and having 6 feeds a day for his age. The problem is sometimes he only wants 50 ml, sometimes 80ml. Also he has one 4 - 4.5 hour sleep at night, then the rest are 2.5 to 3 hours, and only one 4 hour during the day. The rest are maybe and hour or two here or there, he is very alert and awake during the day. I'm worried about overfeeding the the nurse seemed to think thats what I'm doing by his weight gain. Does anyone have any suggestions or advice? I have swapped to Karicare as the nurse thought that my bub may be digesting the other too quick thats why he is hungry all the time.
