Those little cardboard books were well received in DD's bags (well actually they were noodle boxes). She had a Rainbow theme so the books were all different colours.
She also had bubbles, a blow wind mill type thing, paint & paper and a little tye-dye singlet I made for each kid to use when they painted! Also a small spiky ball. Oh and a bath toy but that was because DD got given 3 sets of the same one and I'd never opened them.
I didn't do food for the bags but most kids also took home cake as there was so much left but I don't know if parents or kids ate it.
I'm already planning what theme DS will have and he's not even born yet haha.
