Bottle

My son still has a morning bottle and bedtime bottle, but the problem is he’s still on the newborn teat. I tried to change the treat up but he was choking on it so I swapped it back.

I’ve also noticed that he chokes while drink water, he can’t handle drinking from a straw cup because the flow is too quick.

Is this something that’s normal?

He suffered with reflux when he was younger so I don’t know if that’s left lasting damage.

He’s also the world worst eater picks at things hardly ever has more than one bite on a sitting.

Any advice would be brilliant.
