Her latest stories, just wow! The emotional damage she is causing not only to Tallulah but to Betsy. Golden child/Scapegoat or favouritism causes issues for all the children, even the favourite. They are burdened with the weight of expectation and resented by their siblings.
She is a truly vile parent.
Oh and allowing your kids to swear does not make you or them cool. It just makes them seem disrespectful and you lazy.
Eta: In terms of having a favourite; there’s nothing wrong with finding you get along better with one child over another but you should love every one of your children the same. I was on my own with my eldest for a few years, she’s mine and mine only, she’s also the most like me. We have masses in common, the same sense of humour and I understand her personality as it’s exactly like mine. She’s my best friend. But, and this is the important thing, I love the rest of them equally and because I know I get along better naturally with my eldest I make a concerted effort to find ways to bond with the younger ones, I spend time listening to them so I better understand what they need from me and find the best ways of communicating with them. I’ve found something with each of them we can bond over, something that is just ours. For me this is the minimum they can expect from the one person supposed to love them above all others.
