My 6 week old up until last week was having about 90ml of forumla 6 times a day but we started to up this to 120ml as he seemed hungry more often. He weighed 7lb 15ozs at birth but this dropped to 6lb 13ozs. He has increased his weight and at his 6 week check on Friday he was 9lb 12ozs. However, he has dropped from 25% to 9% on the percentile chart since he was weighed 11 days earlier. The doctor advised me to feed him 180mls 6 times a day. However, this seems a huge amount he struggles with the 120mls as it is. We upped it to 150mls and it takes him two goes to finish it over an hour an a half, he has a sleep inbetween for about half an hour. Can I ask how often and how much your 6 week old LO are having? Thanks.
