Here goes! Have never posted here before and am ready to be told I am being rubbish or just fussing.
DN(2) has a lovely, sweet personality. She's always willing to share. My DD (3) is ok sharing 'normal' toys but is possessive when things are brand new. I personally think this is quite normal for her age. I encourage her to be kind to others but think it's ok for her to want to keep a new gift to herself for a while.
At Christmas I found this quite stressful. Dsis let DN 'help' unwrap my child's gifts and tried to make DD share instantly. My DD was not happy and I was not willing to force her to share her new presents. DD did however play with her cousin's new toys but only after asking and only if DN was happy. My Dsis felt that this was unfair which I can understand a bit but FWIW my older DSs were very kind letting their little cousin have a go with all their new big boy things.
Dsis and DN are coming to DDs forth birthday party on Saturday and staying for the weekend. I'm not sure how to avoid any upset. I really want it to be a happy time.
Should I have a chat with Dsis or AIBU not to make DD share her presents.
