I once babysit my baby cousin when my Auntie was busy doing chores, and when me and my cousin were about to go to the kitchen, my cousin accidentally bumped her head on the counter and guess what, My Auntie and my Mom were extremely mad at me while my cousin is just there crying because of the bump and also me crying for not knowing what did I do wrong in the beginning, but tbh that little cousin of mine broke a lot of my most precious toys that I kept when I was still 6 years old so I kinda hate her a bit because of that(⌐■-■)
Oh my, that's such a bad experience. Children can be such a handful. It's unfair that they dumped the blame on you for that accident.
(I'm the youngest cousin and we have a huge age gap so almost all them already have a family and there are lots of babies in the fam) I can testify that soooo many accidents can happen because babies are unpredictable. And YES, that includes tripping while holding a baby. They can suddenly try to jump from your arm or move so much that BAAAM! You tripped. After such experience, of course, only then will you learn what you can do to avoid similar accidents from happening. And you'll be learning everyday.
I swear, when I was babysitting my nephew there is this one moment—ONLY FOR A SECOND, when I put my nephew's toy back on the box and he suddenly decided to bend backwards while I was holding him. We tripped and both of us cried lol. Even long time parents can't prevent themselves from making mistakes. Wooyoung being bad at parenting which he's doing for the first time is quite realistic (≧▽≦)
