DS is 4 next month and has only been toilet trained since August. I'm a single parent and he has no male parental figure in his life, no one he would have witnessed going for a wee anyway! He's always weed sitting down but yesterday I caught him weeing standing up. Where would he have got this from? Would nursery have taught him to do this?!
I imagine he has seen other boys do it at nursery or they have talked about it amongst themselves. All the boys at my son's nursery are all very proud they can wee standing up so it does encourage all the boys to do it.
Unless you have seen other things that point towards concern, I would not worry.
Totally normal, he would have seen other boys at nursery. My son went from me teaching him to wee sitting down to standing up within about 2 weeks once he had seen my dh going. It makes life easier for alfresco wees!
No they don't, ds nearly 6 has sat down, just recently has been standing up, probably after seeing some of the boys at school. No not everyone shuts the door, he certainly does not when he goes to the toilet.
