My heart goes out to you Angelina for all that you are going through. My husband (Stephen) is the mm person in our life.
We had a very lazy morning laying in bed until about 8 am and chatting. I told Stephen about your posting and we came to the same thought.
A memory book is a wonderful idea. I did one for my mother in law when Stephen's dad died (just old pictures and a few bits from the merchant navy books that she had kept)
Stephen said that he thought it great but would hate it if it was done behind his back when he was still around. If John is up to doing this for Erin and Teagan then it may be quite nice to spend some of his last time doing something that is important to him and will be very, very important to his children especialy later on.
If he cannot face this then maybe you can transcribe his feelings into the "book"
If you decide to create the memory "whatever" don't forget favourite tunes "I can't believe you and Dad listened to this rubbish" "Oops you mean this was recorded in YOUR DAY.
Yes Yes Yes ask everybody to contribute why should we have to wait for a loved one to die before we celebrate their life.
Your girls should know how special their Daddy was before he had to leave them
I hope you can both get through the next few weeks with all the strength that you can muster.
