My baby sister is afraid of my dad

Alexis

So I’m 20, and my mom had just given birth to my baby sister Oct 8,2017. I’m not really home much but when I am, I try to help out with the baby & I swear likes me alittle more than my dad. Like any time my dad babysit the baby while my mom is at work, she goes off... like super off! I was wondering any tips for my dad, just so he doesn’t get frustrated with the baby? And bc on Sunday I have to be back in Denton for college for two weeks. LOL
