I have a two year old niece (my sister's daughter) and she's finally warmed up to me. She used to always act like she hated me since she was born but finally something clicked a few months ago. Now she's incredibly open and affectionate with me and it's awesome! My son is also super close to my sister.

I have a two year old nephew (SIL's son) and I never see him. But we don't get along with SIL either.

Are you close to your nieces/nephews? Are your child(ren) close to their aunts/uncles?
