First of all, I want to say that no one has a right to judge your husband for his actions, while tragic, these things happen. Even if he was there, something still could have gone wrong. Accidents happen unfortunately.

I am so sorry for your loss of dear Leo. I remember his introduction thread and how happy you guys were to have him. May the handsome little boy rest in peace. I am again, so sorry and I hope your husbands guilt fades soon. (((hugs)))
