I remember being told by a carer at DS1s childcare centre that she was concerned that he didn't talk. I was also told by his kindergarten teacher that she thought he should repeat as he was "immature".

He is now 16 and excelling in school - talks rather eloquently, is mature, a great leader at his school and cadets, and (I say rather smugly) doing 2 units of specialist mathematics, chemistry and physics for year 11 & 12 and achieving great results.... not bad for an immature kid who didn't talk.

My thoughts: maybe he had nothing to say to you lady and, point me in the direction of a "mature" 4 year old!!!

Baby's and kids work to their own timelines.

Lastly: stop bragging about all that sleeping - I feel absolutely blessed to get 5 straight hours of sleep!!
