I totally underestimated the change to Yr 1. Someone warned me before she started school that she might turn in to a monster. She didn't last year (tho' it wasn't perfect) but this year, some days she is.
Horrendous behaviour, I can't do anything right, total crying jags about the tiniest thing. We had parent's evening last week, and she seems to be fine at school. She is also fine while at the childminders, but if it's a day I pick her up, or after the childminders she is foul.
I've discovered, accidentally!, that if we do something a bit constructive together it helps. So finding sheet music on the internet that I play on her recorder and then we sing together. Or a crafty thing. I need to think of some more - I had been mostly leaving her to play by herself, because that was fine before - but now it's a bit more like having a toddler and needing to organise fun stuff to do.
It is weird - starting Reception really messed up her sleep, but that is mainly fine now. I did take her to bed at 5.30 ther other day! 7 has been her 'normal' bedtime for a while, and I am mixing that up with a lot of 6.30s at the mo.
Last year they had weeks of half days. I really wish we could have had a bit of that this year. This is real school, a bit of 'golden time' on a friday, and they do do fun things, but dd has to be 'switched on' a lot of more of the day and it's obviously taking it out of her. I do feel bad that she is obviously so tired, but I also need her to know her behaviour is awful. So I try to point that out, but not get ratty with her (but it is really hard).
