That is completely amazing. I strongly believe children do see things we don't. How wonderful of Connor to be able to tell you. Cherish that, write it down.
I have 2 girls, but it's my youngest (she is 3) who has on 2 occasions lead me to believe she sees Nathan. Both times I was blown away and both time were fleeting. The one time was days after he died and she fell asleep on my bed. Very uncharacteristic of her. It was mid day. She woke up and said she saw Nathan. When i questioned her, she dismissed it.
The other time was in the summer, camping. It was pouring rain and her and I were in the car. She looked at me and said--this is where Nathan sits--and pointed between her and her sisters carseat. the little space between them. Again, when I questioned her, she looked at me like I was silly.
Very very cool. I am so thankful for those moments.

Thank you for the beautiful siggy Renee
