Ladies what are some good things to get a 6 yr old for his birthday. My adopted sister is having my nephew a party this weekend and I'm last minute shopper he has just about anything he wants but if I ask her she won't tell me what he likes or anything cuz she doesn't like ppl to feel obligated to bring a gift even though he's my nephew and this is about the only time I get the chance to see him. Birthdays are huge for me because it's a special day for the entire family so money is not an issue.
