Hello, I have a 11 month old DD and a 10 yo DSD. Relationship has always been good, I've known DSD since she was 3. She's always been great with my DD, until the last few weeks when she gets v.jealous of her to the point where she's sometimes mean and shouts at her.
We always make sure she has a lot of alone time with my DH, and that we also do things as a family. I know this is pretty normal, but any ideas to improve the situation would be very welcome.
DSD is with us 75% of weekends and a night or two mid week.
