5 year old change in behaviour

[MadeInCornwallx3]

My (just) five year old ds has always been the most lovely boy. Quite shy and sensitive, but kind, thoughtful, and well behaved.

He started school in September and seems to have changed overnight. As far as I can tell he still behaves beautifully at school but at home it's a different story.

The slightest thing doesn't go his way and he loses it. Screaming, shouting, breaking his toys, getting upset, it's awful.

He also gets upset and scratches his own face.

Once the temper passes he's back to lovely again - until the next time.

I'm at my wits end, I've tried reasoning with him, shouting at him, sending him to his room (where the temper gets worse) but it's exhausting.

I'm 10 weeks pregnant and suffering badly so the timing is not good. He also has a 2yo sister who is super chilled (most of the time!).

I adore him, and he's a beautiful person inside and out but I need to help him control his temper and emotions, as well as stopping the scratching.

Is this normal? A phase? Cause for concern?

Help!

Completely normal,. Just think of him at school all day, like a little volcano, all those times he's maybe felt negative and held it in or held back emotions, so when he gets home to his safe place and safe mummy he erupts, it'll pass with time, just erasure him you understand maybe he's tired, had a tough day, maybe arrange to do something he enjoys when he gets home, if you can something calm or maybe energetic depends on your son.

@laura6032 Thank you for your response. He's my first child so I've never been through the 'starting school' transition before.

I'm hopeful it's just a phase as it's really not nice for anyone! I think a lot of the time it might be about attention also. He's pretty quiet, so I suspect he's not the most 'noticed' one in the classroom.

My boy just started school to and is the same, all the teachers say he's great, well mannered, well behaved, but sometimes he explodes when he gets home, and it's really tough on everyone absolutely, I'm sure he'll grow out of it. I try to do something he enjoys and sometimes that's simply watching a cartoon to chill xx
