At pick up today. I was stood in the playground and her class where with their TA. Their TA said who can see their grown up. (She is 5,Y1). I saw that my DD said something to her and her TA responded, so I presume she said she could see me. Next thing, my DD has left the line and is moving fast towards another part of the playground which is higher up, out of sight.(juniors pick up part) I thought where is she going? So followed her up as it was very very busy and I couldn’t see her through the crowd at first. I caught up to her and she’d gone inside so I waited for a while. Turns out she’d forgotten her water bottle and her TA told her to go up there and get it. (Their classroom is up that way but they come out of different doors at pick up time). I thought this was bad that the TA let her leave the line, go to another part of the school where I wouldn’t have been able to see her and by herself. She wouldn’t go with anyone else I know this but she is only 5 and it was very very busy and no one was with her. Her TA hadn’t seen me, so didn’t know that I’d gone to follow her, so when we came back down she wouldn’t have been aware that she was being dismissed to the correct parent if I hadn’t have waved to show I was with my daughter. So for all she knew, she could have gone with someone else. Aibu to think this is bad or am I over thinking?
