The health visitor has diagnosed Thomas as having colic. She asvised me to try him on infacol and to change his milk over to comfort milk (cow & gate). I was reluctant to change milk incase it upset the baby's stomach or disrupted his routine but the HV insisted that Thomas wouldn't notice the difference. I tried the infacol and it helped for about a week so I decided to change his milk on Sunday. He has gone from having 120-150ml every 4ish hours to having 60-90ml every 2 hours. I think because the comfort milk is thicker that he is having to work harder to suck the milk through the teat so he is giving up. I started him off on gripe water yesterday but it doesn't seem to be making a difference. He isn't bringing any wind up either, just the odd burp here and there. He is on the tommee tippee closer to nature size 1 teats and I was wandering if changing to stage 2 teats would help and make a difference? It says not to use them until 3 months though and Thomas is only 6 weeks old. I just don't want to do anything wrong and make things worse.
