Hi All, A friend of mine has a 6week old baby boy and SIL and I are worried that she doesnt feed him enough. SIL was at a lunch with them on Saturday and bubs was only fed for 5mins during a 4hr period. They were here the other week and bubs was only fed for 2mins twice in a 3hr period. The mum said that he is 4.5kg which sounds good but when he was born he was around 4kgs (8lb9oz). Now as I did not get to feed much with DD as she had lots of wind problems I dont want to judge but am a little concerned. Bubs also sleeps LOTS and doesnt really have any awake periods (longest time awake is about 10mins). Just want some opinions so I know if I need to be worried or not. Thanks.
