Sorry for long post!
OH and I have 2 children, 3.5yr old and 10week old. OH also has a child from previous relationship (coming up 9) who we had every week until our 3yr old was born at which point all contact ceased (Not our choice). We have recently been contacted by a social worker who is involved with his ex's family who has offered to help restablish contact with his first born, this will be done through them as OH/ex-p don't get on. My question is how do we explain this to our 3yr old? She has really struggled with the arrival of her younger sibling and I am concerned that another big change in her life while shes still adjusting to the first is going to completely throw her. I know kids are amazingly resilient and I'm really keen for us to reconnect with step-child so does anyone have any experience or tips on explaining this to her and/or introducing them?
