Mean toddler

Ok so my mom fusses because I call my daughter mean 😂 but she is so mean to ppl she doesn't really know. I know they all go through phases but Sunday at church..they were trying to fit her for a sheep costume and she went ape shit...crying and screaming in church. She wouldn't even let the seamstress write her name on the tag..pushed her hands away. It's just embarrassing and I'm trying to teach her that that's not nice..but lord..and the looks she gives ppl sometimes..wow! I hope this phase passes quickly!
