Why doesn't my cat like me petting her litter?

My cat is nursing a litter of 4, and they're 3 weeks old as of now, but the mother cat hates it whenever I try to pet them and moves them away from my hand, but completely trusts me with belly rubs & such, and I'm just confused why that's the only thing she doesn't trust me with.
