Aurelia sleeps around 2.5 hours spread across 3 naps usually - don't hate me tho, she's still waking at night for her 2 hourly feeds at the mo 
right, seriously need input please on a) whether aibu and b) what i should do
First time back at Felix's music classes since A was born and he loves it, the staff have been very welcoming and helpful (even lend me a buggy for her to sit in as i can't get our twin pram up the stairs) and A enjoys sitting quietly watching the class.
Should have been perfect but A is plagued by the same few annoying toddlers in the class almost non-stop 
i actually wouldn't mind, after all toddlers will be toddlers but the parents just let me do 90% of the 'no, please don't give her that bracelet', 'no, please don't take her toy' 'no, please don't push the buggy' etc etc ad infinitum - each time i'm having to leave Felix on his own (we're moving all round the class so i'm often not next to aurelia) when most of them only have their toddler to look after - so why the hell aren't they?? they finally roll up after a minute with a simpering look as if i should be thinking their toddler tearing my baby's toy away for the 5th time is cute.
aibu to expect the parents of these toddlers to figure out a way of explaining to their toddler that its not acceptable to manhandle Aurelia and her stuff - or at the very least, move their bloody arses a bit quicker to stop them when they do it?
today's class was so tiresome i'm in two minds about signing up for the next half term, which would be a shame as Felix adores it.
if i'm not being unreasonable - what to do?
am wondering whether to have a chat with the staff to see if they can say something - or would be silly? nb, i've taken along 3 friends with their children so i'm actually putting quite a bit of business their way.
or should i just say something to each of the parents - it's pretty much the same 3 toddlers who do it most of the time.
