DD 4 had her first day at school today, her sister and brother also attend here.
When I picked her up she was upset and quiet in the car. I left it a while to ask her how her day had been. She said she was told off and had to sit on her own for 5 minutes until she stopped crying. I presumed she was embellishing whatever had happened and made a note to speak to the teacher tomorrow (thinking that would be ridiculous on her first day at school!)
DD(9) came out of school and launched into an almighty tirade about DD4 getting in trouble and being shouted at. Her story is that DD4 had spotted DD9 through the foundation gate and called her over, they were hugging through the gate and DD4s TA came over and told DD9 to move back into her bit of the playground and told DD4 to move away from the gate. DD9 and DD moved off but DD4 went to the other gate (foundation playground is in the big playground but fenced off) and called her sister again. DD9 says that at this point the TA shouted at DD4 to move away from the gate, got hold of her by her arm and pulled her towards her. DD4 starts crying and runs off, TA then grabs her again and puts her on the bench on her own for 5 minutes (crying) until playtime is over.
After this story I'm 

at DD9 thinking there is major embellishment going on. There were no staff in foundation when I asked at the office but the head came out to speak to me. She had already been informed by DD4s teacher what had happened and backed up DD9s version....except she said she wasn't aware if DD had been grabbed and didn't think she would've been left alone on the bench crying (DD9 swears blind she was as does DD4). The head was also surprised I hadn't been told at pick up.
I have asked the head to get clarification as to what happened exactly and I will go in tomorrow to discuss.
AIBU to think you don't shout or grab a 4yr old on their first day of school? The head said Dd4 was having a tantrum and that's why she was put in time out. She also said DD4 was climbing the gate (it's a waist height u bend one, there's no where to climb it!) and that if DD was grabbed it was because the TA didn't want her to fall.
I'm fucking upset that DD has had such a crappy first day at school! Is this normal crowd control with foundation kids?
