My son is 5 has had no formal education of any kind as compulsory school doesn't start here for another couple of years.
He can recognizes numbers to about 10 but no letters or words, he knows English as we are a bilingual family but I'm sure his use will be far behind that of his peers.
potty training wise he is in pullups, still using them to poop, but okay for wee, he should be okay at school in underpants, what happens when he has an accident?
What should a 5 year old know to 'fit in' with other children of the same age in the uk?
