I believe that Gabriel knew his sister as much as he knew us. He wasn't deaf, he could hear. He could hear our voices, our cries, our prayers, our wishes and my heart. He knew we loved him, he listened to us talking to him telling him all about our lives. He could feel the presense of our friends and family around us and could hear the voices of everyone that loved him so dearly.
Evelyn was less than a year old when we found out we were expecting again, she was only 18 months old when Gabriel was born. Yes she came to the hospital in the middle of the night to meet her brother. No she doesn't understand, she's far too young. In fact, when she was at the hospital she had a look of "What... is... that???" most of the time she was there. So she's handling it fine, sometimes she seems to understand when we have tough days, or rough moments. Most of the time she is completely clueless.

When she asks about him, we will answer in the best way we can, the best way we feel she will understand. Telling her that Gabriel is her brother and that he plays with the angels instead of here with us. Then we can explain that he was very sick and had to go where he could be healthy again. Then we will explain what was wrong with him. Hopefully we can continue adding details as she is ready for them. Eventually she'll know the entire story.
We have shadow boxes, pictures, and other memorabilia in our home, she'll see all of that regularly. I love to scrapbook and when I found out I was pregnant I started one for him. Sadly that book has turned into a memorial. I can't get myself to work on it to get it finished... I want to, I'm just not ready yet. I've created a folder where I keep everything I need to put in there, when I'm ready I'll finish it. Someday, she'll have that book to look at and see the entire story, every ultrasound, doctor appointment, flat item we've recieved, and all my blogs (I've been printing them and putting them in there as we go.) She'll have plenty of things to remind her that he existed.
We hope that by keeping him very alive in our hearts and our lives, she will someday cherish having an angel brother as much as we cherish having an angel son. My secret wish is that someday - when she's old enough - she'll want to get a tattoo to commemorate him. (I love tattoos and that explains a lot haha, she may hate them and that would be ok too).
My point is that I hope she will feel his love, I hope someday she'll mention him to me, ask questions, or talk to other people about him. I have recieved emails, comments, and messages from people who have referred to their "angel siblings" and I hope someday, that will be Evelyn.
It would touch my heart to hear her say "I have a brother, he is all around me, he's my guardian angel..."
