People beating their kids outside the meeting for just being kids, not being bad. It used to really piss me off.
I knew a lady who used to take her 1 year old to a bedroom during a home bookstudy and beat the crap out of her for squirming and cooing. Her young son she would twist his ear around if he couldn't sit still. I was a teenager at the time and it used to upset me so bad I would start crying. I never understood why they didn't stop to think that certain behaviors of babies & young children are part of the different growing phases and should not have been punished.
When my kids were really little and would start squirming or cooing I used to pick them up and stand at the back of the hall and rock them and just gently say shhhh. Kids aren't stupid and they don't need to be beat for just being human.
Since I was reinstated at the time and didn't have a husband attending meetings with me, I would get dirty looks from people, and they would complain to the attendants that me and my kids were being disruptive. They wouldn't have dared do that to a woman whose husband was at the meeting. They always treated single moms at the meetings differently than the ones who had whole familes at the meetings.
