Our 14 yr old Nephew appears to be completely obssessed with our 3-yr old daughter. When we have family gatherings, he will not leave our daughter's side & is always taking her away from our sight. He also always wants to watch her diaper being changed. Once I had to take her into the bathroom to change her diaper & he had been standing outside the bathroom door with his ear up towards the door when I opened it, he took off running. It is giving me a very uncomfortable feeling - is this normal behavior for a 14-yr old at all? We love our Nephew, and this is the last way that we want to feel about him - but, we need to protect out daughter?? Also, when I ask our Nephew to keep our daughter within my sight - 2 min later, he has taken her off somewhere & looks at me from the corner of his eye - it is more than a creepy feeling that I am having - or am I over-reacting???
