First school party of this academic year.
DS1 has just started reception so it was the child's 5th birthday. All the other children there were 4. It was at big soft play centre.
Almost half of the children were left there alone.
One little girl had a wee accident as she didn't want to ask to go to the toilet and her Mum hadn't shown here where they were before she left.
I spotted another boy holding his genital area and looking uncomfortable - he needed the toilet aswell so I took him. He couldn't even get his trousers down by himself.
A third child had a nasty bump with another child (who wasn't part of the party) and was inconsoleable for about 15 minutes (his parents hadn't left a contact number).
AIBU to think that 4 is too young to be left alone at this sort of party, (especially without leaving a contact number and checking that your child can get to and go to the toilet if they're unlikely to ask anyone else)
