DD & DS will be turning 3 & 1 right around the same time, as will my nieces and nephews (also turning 1 & 3 in the same families).... wondering what would be good gifts to get the kids that both kids could use. They don't necessarily need to be able to play with them together, but should be something the 1 year olds wouldn't be able to choke on.

Any ideas?

Thanks!
