Maybe this isn't a recent thing nd I have just started to notice it since close family nd I have started families but most parents I come across let their kids get away with murder.
To clarify, I don't believe in smacking and think good discipline can be achieved without it.
I would be mortified if my dc acted the way I see many children acting, including my nephews.
Although I would never say anything directly, as I think parenting tactics are very personal choices, it annoys me as I feel like my SIL and BIL kids are setting a bad example for mine.
