My DH was doing some DIY at the weekend, and our toddler was getting involved, like they do. He grabbed a bag and my DH angrily snatched it from him with force, so that he fell onto a glass dish and banged his head and arm. My DH didn't react, and left him crying. I was feeding our baby at the time, and had to pop him down to console our toddler. My sister was there playing with our older daughter, and when we were talking about it later she said she thinks this kind of behaviur is abuse. My husband just said he didnt mean to hurt him and it was an accident. Who's BU, my sister or my husband?
YABU - My sister is right
YANBU - My husband is right
