My partner has gone back to the UK over the Easter half term to visit the grandparents. So as a treat they decide to go swimming. We have three children aged 4, 4 and 2. Both the 4 year olds can swim well unaided and go swimming at least once every week in Switzerland.
They were refused entry into a UK swimming pool, because there weren't three accompanying adults. There was my partner, her father and a 15 year old cousin to accompany them, but they were refused and told this is a UK wide national policy. So we are very thankful to be in CH, where one adult can take three children swimming without anyone batting an eyelid.
What chance does a single parent have in the UK, if they have more than one small child.
