My 16 week old baby boy was 5 wks prem and weighed 3lbs. He was tube fed initially, breast feeding didn't work out so was on ebm until supply ran out at about 6wks. Along the way it was mentioned he had a tongue tie but no one seemed very concerned. He's always been quite a fussy feeder- takes ages over bottle, very gulpy, chews on teat, doesn't form proper seal around teat etc. and is getting worse. He'll be happy and hungry but as soon as I put the bottle to his mouth he screams for half an hour before eventually guzzling it down- nothing else obvious wrong, he's not over tired, he's winded and obviously hungry as he has it in the end. Wondering if tongue tie might be affecting feeding- making him frustrated etc. Anyone else had a similar experience??
