DS is leaving Nursery and we thought it would be nice to mark his leaving by taking in some cupcakes for staff and children. Nursery have agreed this, provided there are not any nuts in the cakes and have advised that children won't be able to eat them on the site. To get around some of this, is am going to put each cupcake in an individual bag for ease of taking home, but the nut thing is worrying me slightly - I'm going to buy the cupcakes from a supermarket and apart from checking warning labels and avoiding cakes with nuts and those made in factories using nuts, is there anything else I should avoid?
