Birthday present for 6 kids

When is the party? how long have you go to organise?

As above I suggest the book people, you can get 10 books for £12

Pick the best two for the children your son knows, then pick out the next best 4 to keep for your child, divide the other 4 between the un-known children (they are all good books so nobody is missing gout)

I would then put something else with the books for the two friends but do not spend more than £5 each total on them.

They are nursery friends they will not be expecting much.
