Not a fan but it is unfair to assume that Sopha is not concerned/doing anything about Ronnie’s speech development. My two oldest were very early talkers, my youngest has disordered language development, said very little at Ronnie’s age and needed support all through primary school. Gobby little teenager now though.
There was a lot of self-blame in the early days on my part even though she was parented exactly the same as her sisters, so IF Ronnie does have a speech delay Hinch may not feel comfortable talking about it. I don’t think there is anything to be gained by comparing him to Rex who is a completely different personality.
