DS1 (3) is good friends with another little boy at nursery. He seems to really enjoy his company and the nursery staff say they spend all day together.
However, I have noticed that the other little boy has become very possessive over DS. I have observed him actively stopping other children playing with DS and when I turn up to collect him he drags DS off and tries to hide him from me and has on occasion thrown things at me (mud, bucket, spade) in an attempt to get me to go away. I'm very kind, but firm and say no, don't throw things and that it's time for DS to go home now but he'll see him again to play tomorrow.
Do you think this is cause for concern? DS1 isn't exactly a shrinking violet personality wise, but he does seem to defer to his friend. He also mentioned that his friend had hit him last week as he hadn't done what he wanted. He said he told the nursery staff about it, but although they said there was a disagreement between the boys they hadn't said DS had been hit.
WWYD? I'm going to mention it to the nursery at pick up today, but what approach should I take?
