I need some advice 🙁

Some tips from anyone who has a baby with reflux.

He is formula feed but recently started choking when I give him a bottle. It is really scary to the point I am dreading next feed because I am scared he will choke and then he starts to cough.

I do feed him in upright position and take breaks in between.

I burp him but he still spits up.

He archers his back and head and when he is sleeping he turns his head always on the right side.

It was all fine the first two weeks but suddenly it is as he doesn’t know how to drink anymore.

He was also a really calm baby and it is like someone switched him.

Some advice?
