Baby 6 months screams and squeals says ah ah but no babbling

[holly2437]

Hi all,

I was wondering if anyone could advise my babi is just turnt 6 months old and since about 4 months old has decided to squeal on the top of his lungs and shriek this replaced the cooing. He does say ah ah ah and little noises also but no consonants.. he can roll both sides tummy and back. He does have reflux/potential allergies unknown told.
