That sounds like a judgmental group book!
We had to leave playgroup early on Monday as she threw about 3 tantrums in 10 minutes. She refused to sleep on the mile walk home then managed to wiggle out of her straps and stand up in her pushchair, then she threw herself backwards when I tried to grab her and I had to throw the umbrella on the floor to catch her. Luckily we were literally across the road from our house so I didn't have to struggle too long holding her, the umbrella and the rain cover she had pulled off, whilst pushing the pram.
DH thinks they might be able to make it back tomorrow, which is better. Trying to sleep in my own bed tonight. Stupidly terrified!
