I'm truly sorry for your loss. The poem brought tears to my eyes as well. I lost my baby earlier this year...the day before my birthday. I was on my way to the vet because I knew she was on her way out and didn't want her to suffer, when she slowly started fading out. Minutes after I reached the vet she died in my arms as I told her what a good girl she was and how much I loved her.
You never stop missing them...but the overwhelming sadness is eventually replaced with happy memories.
Roxy will never replace my other baby girl...but she was never meant to. We love all our babies in different ways...though I feel safe to say we love them all the same amount.
My prayers go out to you and your loved ones. I hope you find comfort in knowing what a wonderful life you offered him.
