I feel bad about making my cousin cry?

I don't LOVE little kids, but I don't hate them either. So please don't think I'm a terrible person because I feel like one :(

I was having lunch with my little cousin who is 1 and my aunt (my uncle's wife) and my little cousin was throwing everything I gave her on the floor and even if she wanted it, I gave it to her but she still threw it on the floor! I know she's in a phase and she's testing the laws of gravity, but it ticked me off so bad that I told her 'Clara no, please stop.' And she stared at me for like five seconds before bursting into tears. My aunt who is a very protective mother took her and told me not to scream at her.

I feel really bad. Please don't think that I'm just not used to little kids, I have a five year old brother and my mom's friends all have babies so the house is always filled with children. I'm just very insensitive sometimes.

I feel bad about making my cousin cry and now I think that my aunt hates me...
