Since just before half-term, my lovely DS has undergone a transformation. He has suddenly become upset (hysterical) when I drop him at school. He's in reception. He refused to go to bed for the past week. He's had tantrums twice in the middle of the night - he is normally a brilliant sleeper. He's been playing up in the day, too, refusing to eat his breakfast, being horrible to his little sister and generally pushing boundaries.
I can't see a reason for this. Nothing has changed. He loves school & has been fine about going all year. Everything is stable at home, and he has good friends. His teacher is really surprised when I tell her he's acting up at home as he is very good - he is normally a really sweet little lad.
The only thing I can think of is that he is jealous of his DS. She is 2.5 but up until about 2 years old was a nightmare baby - she's lovely now, very cute and funny and I wonder if he didn't feel jealous of her until now because she wasn't a "threat", if you see what I mean. He was always the golden child until recently...
I can't think of anything else. I am getting worried about him now - dropped him back this morning after half-term and his teacher had to peel him off me and he was hysterical. Really distressing.
Is it common for little boys to go through a phase at this time - he's 5.5? Help - need some advice!
