My 3 month LO has always got excited about his feeds, as soon as you get the bin, he’s like an excited puppy. However recently, this excited behaviour has changed. He stiffens up like a plank of wood, you would think he’s refusing his bottle, but as soon as the teat is close to him he lunges for it and feeds like he has never been fed. When we stop him to burp him half way through, he seriously protests, it’s like he’s throwing a tantrum. I have tried dummy but he spits this across the room, so I have to try other distractions, but getting him through burping is becoming harder. Is this just a phase? part of learning? He’s just come out of a growth spurt so I know it’s not that. It’s just very strange and different to how he fed before.
