My 8 1/2 year old girls just left me side. She has been in here all evening snuggling while we played Gardens of Time on FB.
My 5 yr. old grandson will lay by me on the bed and watch some TV but as for just sitting with me to snuggle...he really doesn't do that too much unless he is feeling bad.
My friend has a son who still likes to snuggle, he is nearly 12. She was turned into the state last year by some parents who saw it at an activity and said it was highly inappropriate for a young man that age to be acting like that around his mom. They insinuated they were having a sexual relationship. The state dismissed the referral but the boy and mom both have to do counseling once a week for a year.
The hubby actually won full custody by bringing it up in court how he felt it was inappropriate for his son to still be doing that. She has suffered and cried over this.
So I do believe that society will notice if it is past the point that they feel it is acceptable.
It's cute when a little one does it but a young man? I don't know when the cut off point would be for sure though.
