"... nobody in particular runs the group and we’re just left to our own devices, the church has no input whatsoever they just let us use the hall. we buy the biscuits and milk and what not, get all the toys out ourselves and put them away etc
When I told the office in a complete state of shock they were completely dismissive of the issue and said how they leave the doors open for mothers and children to easily access the group and acted like it was nothing to do with them"
@Bornunderpunches - These two things are the key issue - it is up to whoever is running the group to decide whether the doors are kept closed. If it is the parents then the you need to speak to the other parents and get them to agree that the doors should be closed.
If the church has nothing to do with the group besides allowing use of the hall then it's not up to the people in the office whether the doors are open or not.
If the church runs the group, then it is absolutely a safeguarding issue that needs to be addressed.
People are right, that it is your responsibility to keep an eye on your child like soft play, but every single soft play I ever took my kids to had safety doors or barriers to stop children running out or non-customers getting in.
Keeping the doors closed is not just about stopping children running out, it is also about deterring people coming in who shouldn't be there.
There are also a number of other issues which need to be considered - is there a sign in / out sheet and who holds it? That is standard fire safety regulations.
You say you use the church's toys - is that covered under the church's public liability should there be any issues or if they space is not being used under an official hire agreement or should the group have their own liability insurance?
