Thinking about it more, the one thing that changed a month ago is that many of his friends left nursery to move to school and he has been left behind with some of his friends. At the same time, new younger children have joined his group. The nursery told us he is very caring towards them. We try to arrange play dates with them but they have their own lives with new school friends.
He goes 3 days a week. He has tantrums about not going in but loves it once there. On his non nursery days he has tantrums about wanting to go in.
We go to the playground with him every day when he’s not at nursery. We bake together, draw, paint, play games, reading books, role play etc. He loves his sibling but does get frustrated by him once or twice a day eg if sibling grabs an toy he is playing with, and I make a show of pretend telling off his sibling so that he knows I care about him.
We go OTT on praising good behaviour. We give him choices wherever possible eg clothes, but he tantrums that it’s not what he wants. He will want for example something that’s still wet from washing and will scream that he wants to wear it despite giving him 3 other choices.
Sometimes when he tantrums about breakfast we go downstairs without him and tell him to join us when he’s ready. He won’t and will continue to sulk. He would rather not eat and be hungry, but then continues to tantrum because he’s hungry and make the rest of the day miserable for all of us.
He gets so much 1-1 time. Our lives revolve around keeping him happy and safe. But I feel like we have gone wrong somewhere.
