I just went to my sons 2 month checkup on Friday he weighed 10.8 and has always had a lot of gas the doc suggested I try giving lactose free formula for 2 weeks to see if my son would put on weight and have less gas. He thinks he is lactose intolerant which I thought was weird b/c neither me or my husband are? I want to continue breastfeeding and fear if I stop for 2 weeks it will be hard to get my milk supply back. I didn't think 10.8 was under weight? My son also had green poop today and it is usually yellow so what does that mean??? Also my son seems to nurse every night from about 7-11 he latches on and then pulls of and grunts a lot but wants to continue to nurse I try burping him and sometimes he does but he continues to want to nurse. Do you think he is not getting enough milk or is this normal?
