DS1 (4) started reception in September and is generally a nice, relatively well behaved boy. He can be a monkey like all little boys but no problems at school, gets on with his little brother, plays nicely etc, bit lazy but nothing to worry about.
However something seems to have snapped with him lately and he is having what I can only describe as rages, stemming from apparently nothing. He will repeatedly shout 'No' very loudly and abruptly - not respond to anything (either being told off or softly softly lets have a cuddle approach). He will kick, hit and scratch (not great as 7 mths preg with dc3), tell us to go away (which we do but he keeps going on). Nothing gets through to him (talking about nice things/ bribery/ threats/ trying to cuddle).
Yesterday I was walking home from school with him and all I said was ' how was your day' and 'really looking forward to seeing you in the play tomorrow' - he threw his lunchbox down, did the 'No' thing and ran ahead of me all the way home (no roads to cross). He was trying to hit me and when I asked why he said he didn't want me to ask him 'how he was'.
Then last night he woke up at 11.30 and we had an hour of this - ds2 had a temperature as it was and ended up in our room as he was so upset (they share). DS was trying to kick my tummy, yelling as loud as he could (great as we live in a Victorian terrace next to a social worker). He was crying, responding to nothing (mainly us trying to give him a cuddle/ find out what was wrong).. so so angry. I am hormonal and got upset and it was all a big mess. I had to push him away from me at one point as he was trying to thump me and then he said I was hitting him (which I wasn't and wouldn't ever). I am very worried as it is all so out of character and also because I am worried what the neighbours think.
Sorry this is a bit of an essay - part of me wonders whether this is just him trying to assert himself as he starts school, but part of me wonders whether there is something very wrong. He does also have night terrors but they are totally different as he is asleep for those. Any thoughts welcome
