My 2.8 year old dd goes to a 'mini-movers' dance class each week and this weekend they're part of the dance school's annual show doing one dance - nothing too serious, just fun, obviously! Last week there was a rehearsal at the little theatre where they're doing the performance and as always, we were asked to drop her off and leave and pick her up in an hour (usually it's 45 mins). There was the usual lady who takes their class with them, plus their usual two helpers and another couple of mums. Off they went backstage to see where their dressing room would be etc.
I went back to pick her up and found my way to the dressing room where the children in her group all were (they'd done their run through etc) and couldn't see my dd anywhere. All the adults there looked at me blankly; one of the usual chaperones told me she's probably in the toilet round the corner so took me there; a little boy tagged along with her as he needed the toilet so she stopped to take him to the loo - I'm then starting to get a little frantic as she could've been anywhere and no-one appeared to have any idea she wasn't even there. So proceeded to search in some rooms near the toilets, other changing rooms; I went back to the room where all the others were and two little boys her age told me she'd gone out of the door and pointed which way.
I found her playing at the bottom of a stairwell about to get onto a lift (having a great time in her eyes!).
I left straight away with her, pretty fuming (and bloody relieved I'd found her). No-one got in touch to ask whether I'd found her ok (I know I should've gone back and said); a register of who's there is always, and was that day, always taken.
I feel as though I shouldn't have left her - but she's been going for quite a few months and there's been no problems leaving her when it's the usual class - and we were told that that's what happens that we're expected to leave them at this rehearsal and come back for them, they're being looked after etc.
I was going to ring the lady who's in charge of the school just to make her aware of what had happened (and let her know I'll be on door duty of their dressing room at the show even though we've been asked not to be back stage, just in case of any escapees!). Or am I overreacting?
