A likes his new nursery more than the old one, which he loved.
Spotty just be honest with them. You don't think he's ready, you don't need it for work, so you'd like to try again when he's older rather make everything a battle for them.
Yay R.
Hales I find a choice between doing what he's told or being shut in his room is the only way with A right now. With a certain amount of manhandling into clothes or onto the toilet. Giving very limited choice might work, eg between 2 outfits. Or let her choose the night before and lay it out ready.
Don't forget that making choices is a skill they have to learn, not natural. Sometimes it's overwhelming for them.
