The tot group I went to with Aaron cost £1 and 50p per extra child. They used to fill the hall with toys and let them play for ages, also had a table with something crafty to do, each week changed from painting to sticking etc. Then they'd pack the craft stuff away and puzzle tables to set it up for the kids to have snacks and a drink (usually raisins and breadsticks). Then they'd bring out big cars out for the kids to go mad on around the hall and then they'd have nursery rhymes and we'd go home.
