Ds2, 13 weeks, was weighed today after a gap of several weeks, in which time his weight has more or less plateaued. Having started on the 75th percentile he is now on the 25th. He had tongue tie which was operated on when he was 6 weeks old, but So feel his latch is still peculiar, especially on one side. No doubt this is the root of the problem. Trouble is I've been to the BF clinic and followed their advice re position, pinching the boob to get a good latch, breast compression etc,.but it seems none of it has helped much. Clinic are now suggesting I try mixed feeding, which I am loath to do, not least because on the occasions I've tried he has refused to take a bottle. Has anyone else experienced similar problems, and did you find any solutions that worked - without introducing formula?
