I feel with some children it’s always lurking.
Two of our children I’m completely confident in saying, that it’s extremely unlikely to ever happen. One daughter, however is very sensitive, often misinterprets things which are said, is very aware of everything needing to be fair, and has periods of being cool with us.
My way of dealing with it, is to pretend I haven’t noticed anything, and things gradually go back to normal,
We once came close when we took our youngest daughter and her children away for a couple of days one year, to give them a bit of a break. Our other daughter and her husband had taken their children to Florida for three weeks and we didn’t think she’d begrudge her sister three nights in Cornwall, we were wrong, it caused a massive row.
We tread very carefully with her, I’m partly annoyed with her, and partly feel worried about her, I just hope that one day she won’t walk away.
