Hi
My dsis has a ds who is 18 months old, and he is lovely. My ds2 is 3 years old, and is less than impressed with his cousin. Naturally, dn will often try to take toys from ds2. This doesn't bother me, it's what babies and toddlers do sometimes. However, dsis does not intervene when dn does this. Instead she says to my ds "Mini Shelves, you are bigger than your cousin. If you don't want him to take the toy you must keep hold of it". She never says "no" to dn. If I am present I will find another toy to give dn and return the stolen goods to ds.
It happened a few days ago and dsis said to me "I think we are going to have to talk to Mini Shelves and tell him since he is bigger than his cousin he should not let him take things from him." I told her that I disagreed, and that Dn should be told by the supervising adult that he is not to take toys from other children. She mumbled "I suppose so', and then we got chatting about other things.
Now I have vocalised my opinion I am second guessing myself. I don't think IABU, but I feel I should get others perspective before deciding for sure how to deal with any future toy disputes. Dsis and I are fine BTW, no falling out or tension during that conversation or afterwards.
