DD2 is 3 months old and has terrible wind. We have switched to a comfort formula and it seems to have made a difference. We are using MAM bottles and No2 2-4m teats. The problem is that DD has to suck quite hard to get the milk and is taking forever to take a reasonable amount. She gets frustrated and starts crying or falls asleep. I bought the variflow and the No3 teats thinking that they would solve the problem but they are way too fast for her. She just ends up wearing most of the milk as it splutters out the side of her mouth.
Would be very grateful for peoples suggestions of what bottles/teats worked for them if they have experience of thickened formula.
