Hi,
DD took the arrival of her brother 2 yrs ago very well but these days she is very jealous. She blocks him getting attention by behaving badly herself, it's starting to feel like we're always giving out to her. She does enjoy his company and they are great play companions but you can't say anything positive to him, such as good boy, without her then insisting that she's a bad girl. If he's getting a story read to him she makes sure to interrupt. She's very advanced and verbally agile and has become very sarcastic.
I feel like we are all locked in a negative cycle with this, does anyone have any advice on how to successfully reassure her that we have enough love and affection (we've told her this hundreds of times!) for them both. Is this a phase or just basic sibling rivalry? Either way for now I'd really like to ease her hurt feelings about having a brother.
Thanks
