My nephew is turning 3 on Sunday and I need to get him a gift. Also, my sister (his mom) and I had a bit of a spat on vacation two weeks ago so I am trying to pick a nice, considerate birthday gift. Honestly, I am not all that close with him - I know he likes books and toy cars (but he just got a whole bunch of Matchbox cars) but I am not sure what else. Any suggestions? TIA!
