I have a 10 week old baby who has always feed reasonably well. She never really spewed or had wind issues as we winded well and used infacol. Since Saturday she has been incredibly unsettled and screaming with wind after bottles despite being thoroughly winded. The only thing I have changed is to increase bottles to 8oz as she was draining 2 7oz bottles a day. She squeals during feeding if we break to wind. My husband suggested that the prep machine is creating more foam which may be impacting things but I don't understand this sudden onset. Its like a switch has been flipped. Can anyone advise what I may be doing wrong?
