But for me it’s the kind of behaviour I would flag up. Like touching Isabelle’s presents, that’s a no no, I would’ve asked her to pop it back, she’d already been shown it, as it was she then dropped it on the floor and momentarily lost it.
There are lots of little things she does that creepy and lazy just don’t pull her up on, I also don’t remember her ever being this irritating or maybe she is and they cut it out more.
I also have multiple personal experience of ‘older’ children becoming a sibling, either for the first time or already having older siblings already and I’ve not known any to react the way she has. The toddlers, yeah sure but not the 5/6/7/8 year olds. But as you say she’s a product of her environment, I don’t blame the kids either but i say what I see and she’s just been annoying me a ‘soooper doooper’ lot lately!
