DS2 is 4 weeks. He is FF. We are using aptamil first milk, number 1 teat on tommee tippee bottles. He takes 3-4 oz every 3 hrs, which seems pretty good to me, but I was hoping to get him to go 4 hourly by now. He gulps the first half of the feed, then messes about with the rest of it. I usually take the bottle away once he seems to have stopped feeding properly. During and after the feed he seems very uncomfortable: crying, writhing, alternately stretching then drawing his knees up. He is quite farty and hard to burp, despite using infacol. He is occasionally sick, maybe every 2-3 days, but small quantities and no regular possetting. This has got worse over the last few days. I don't know if this is relevant but he was 1 month prem and had a NGT for 1 week. He poos 2-3 times a day and the poos are mustard coloured and like soft scrambled eggs in consistency, ie normal. He really will only sleep for any length of time on his tummy. His weight gain has been very fast: regained birth weight 5lb3 by 10 days, 5lb10 by 15 days, 6lb 14 at 26 days. Midwifes happy with this.
