There aren’t many, but they are important:

You will not be allowed in if you are under the influence of drink or drugs.
One adult relative must be present with the children and must look after them at all times - this is not the volunteers’ job.
Only the agreed number of people are allowed in the Centre   (this means that you cannot bring a friend or other relative with you unless it has previously been agreed and confirmed by all parties)
