I am a step parent to an 11 year old boy and 8 year old girl.
Over recent weeks I have noticed that the 11 year old will want to initiate 'wrestling' with his sister. I will discreetly watch them and I don't see anything overly concerning but it is very physical - rolling around on the floor and climbing over each other. It never escalated to the point where one of them gets injured. Last week we heard the 8 year old say "penis" in a sentence when they were doing it so their father intervened and told them to stop.
I am finding it is making me uncomfortable and I am worried it is going to happen again this weekend when we have them to stay with us.
I am quite clueless to child development and part of me wonders if the 11 year old is enjoying the physical contact with his sister??? Sorry if that sounds bad I just don't know how to word it. My gut instinct is that we need to put a stop to it completely?
Thanks in advance for any advise.
