I really need some advice! I have 5 month old twin boys. Both twins were exclusively breast fed for 6 weeks then I started giving them a bottle of expressed breast milk at 10pm. Twin two took to it fine and has progressed to formula at this time and then half and half feeds at other times of the day. My problem is with twin one. He drank from the Avent bottle for 3 weeks, then refused. Since then I have tried him with two other makes of bottles and all have the same affect - howling, head twisting, refusing to suck. He was a tricky feeder from day one and I was unable to breast feed them together due to having to concentrate solely on twin two in order for him to feed. I am now at the stage of needing to get on with everything else and need to find a way of him drinking from something else. Has anyone found a magic bottle or method of getting tricky feeders to drink from a bottle or should I just try him on some sort of sippy cup, if so which one? HELP!
