I have an 8 month old little baby and he's mainly eating baby food now rather than his bottles. He has a bottle before bedtime and through the night when he wakes for a feed. Everytime he has a bottle he sicks most of it back up and I give him a drink of water with his food and tends to be sick after a drink too. Is this normal. I'm a bit concerned as he's 8 month now and people keep asking me if that should be happening or if I need to get him seen to.
