It seems no matter what we do, my 3 old hates the idea of it. Like I told him as his birthday approached what his party was going to be like and each time I'd mention it he'd scream and say don't want a party. Everything I tell him about and try to prepare him for what we are about to do he wants nothing to do with it. Even things he knows, like we are going to visit Mamaw and Papaw today, don't want to do it. But if we just take him and do something he has fun, but he doesn't want to hear about it lol.
Re: Does your 3 year old do this?
I don't have any experience with this. My daughter does best with plenty of notice, lots of reminders & then talking about it at length (lol!)
But perhaps you should stop giving your son advanced notice about events and see if that helps.
Good luck
