pasta have you ever been in a building when the fire alarm is going off?
Who is going to evacuate them? Who’s specific job role is it to find and herd out unsupervised children that no one actually knows are there - apart from the parent that is in another part of the building.
I’ll tell you. No one.
I teach swimming and we have many supervised drills. All the children are already acccounted for so us teachers directly deal with those. All other adults are asked repeatedly to leave the building at the appropriate exits and meet at the fire points out side.
So any straggerlers are found by chance when staff are exiting the building and urging people to move to the exit. We are told not to go looking in empty rooms, toilets ect .. to just keep moving forward. If the child goes to the toilet or gets stiff legs and decides to go for a little wonder then she is fucked. As NO ONE will be expecting to find her/evacuate her
So yeah , what if there is a fire is a very valid point.
The op relative is making her seven year old some one else’s responsibility.
When people Go to these centres they are usually there for a class (or gym) or to watch some one in a class (adult or child accompanied by a adult) this child is in no register, no class nothing. No one really knows she is there.
And seriously - you CAN NOT expect a complete stranger to look after your child - regardless of your ‘risk assessment’, how would you explain that away ‘oh well I thought she was ok as there was a complete stranger sat near her and I thought she would look after her’
