11 month old baby with reflux

Attn: Joe De Livera
I have an 11 month old baby boy who I'm sure has had some form of reflux since birth. He doesn't spit up a lot just every once in a while after feeding. I mostly hear it come up his throat and he gulps it back down which causes him to cough and cry. It makes it hard for him to feed, he cries and pulls off when this happens. It's especially frustrating for him when the milk lets down. He nurses best when he's tired and calm enough to handle it. He always nurses to sleep. If he's not tired he will only nurse for a few minutes, so I really feel like he's not eating enough. He does eat some solids, but he's pretty fussy with it. He'll eat a little bit and then start screaming until I let him down. I don't if he just gets bored with it or he's in pain. He's very distracted. His sleep is horrible. At night he's up every 2hrs, he'll only go back to sleep after nursing. To get him settled back in his bed I have to walk around rocking him in a cradle hold. If he won't go back in his bed, he sleeps with me and flips and flops all night! So neither of us is sleeping. He recently had and ear infection from a cold and took a round of antibiotics. He's a bit constipated from that and his reflux seems worse. He's been much fussier with eating too. Normally he goes poo pretty regularly. I think the antibiotics really messed him up more. I'm giving him probiotics for the constipation, hopefully it helps. If you could help us at all, with any of this, I know we would both be greatly relieved. Thank you for your time.
