DD (3) got one of those play mats with cars for Christmas. She is at her dad's this weekend. DSS (5) is due here today for the weekend. DD hasn't yet played with the mat as she was with her Dad for Christmas so didn't open presents until new year and then we were visiting family etc and then went back to her dads. Last night, I moved the play mat and a few other presents DD got into the garage. DP asked why I was putting them in the garage and I said that I was going to sort out the playroom this weekend to make space for all the new things and would put them in once it was tidy as there isn't enough space until I've moved some stuff out and this is easier when DD isn't here as she wants to keep everything! DP then got really cross saying that I was moving them so DSS couldn't play with them. I explained why I was putting them in the garage again but said that I wouldn't have let DSS play with them anyway as DD hasn't played with them yet. DSS is not very good at sharing. He takes all his things back to his mums so has nothing to play with here and then brings one thing with him each time. He won't let DD touch it and DP never makes him but expects DD to share all her things.
So AIBU to have put them away? I do encourage DD to share but am beginning to feel that I am being unfair on her making her share all her things when DSS doesn't reciprocate.
