ok it is perfectly normal for them to kiss an goof around together dont worry about it they will play around like that an after a bit they will get bored with it an stop... its a natural normal thing... my daughter an son do that too then they get bored with it an stop... me an my sister did to when we were young so just let it play out.
thanks sandman and margypops for your help!!
they just turned 6 in november. they are indeed very playfull. the kissing thing comes as taking advantage of the oportunity of physical contact at the moment of playing and wrestling or they can be just bored and he starts with it just to see her get annoyed. I have observed them and this is my understanding. since he was litthle he tryed doing it to me and would make a joke out of it. As I told him not to he turned to his sister. What I did tell them was that it is important for the family to love oneanother and show affection but we have to learn to respect personal space and what is a mommy/daddy kiss and a family kiss. what is a good touch bad touch and not let anyone do to you something you don't want or like.
Yes I agree with Sandman the age would help, if you are an affectionate family it could be he is copying, thats what children do, they learn from our behavior, so show him how mom and Dad kiss on the cheek now ,if he is always bugging her as you say it may be time to ask him not to do that .
It would be nice to know how old they are. If they are "young", that is the way they have seen affection being given and that is what they have learned. I think the real question is - is he doing the hugging and kissing to annoy her ?
