Take off their clothes and/or put them on? ie Put on their own shoes? Put on a coat? Pull their trousers down? Ride a scooter? Catch a ball? Brush their teeth? Climb into their own car seat? Get onto the toilet? Make a sandcastle? Use a knife and fork? Walk upstairs like we do (ie not on all fours or by literally hauling himself up one step at a time by pulling on the bannister) and come downstairs facing forwards without holding on.
I ask because ds, who was three last week, cannot do any of the above. The idiot HV seems to think this is perfectly normal, but from the three year olds I see, I don't think it is. I'm honestly not just asking for people to post with equally incompetent just-threes, but wondered what the consensus was.
As for toilet-training, don't go there! I don't think he has any idea he is going to wee at all.
