Does my hedgehog like me?

I've had a hedgehog for a few days now and he seems pretty warmed up to the family already. He comes out when he knows he's going to get a mealworm and he'll let us pick him up no problem. The thing is, whenever someone else holds him, like my mother or father, he always sniffs and explores around but when I hold him he just curls up into a ball and starts sleeping. So I was wondering, does he like me yet or is he still getting used to me?
