just
I'm sorry you have no childhood memorabilia to pass on to your DD
but I'd like to offer this:
If you can't change the circumstances, change your point of view
try and see it this way: your DD never have to grieve over loosing them or braking them. You take that pain and guilt away from her and while it's not nice for you now, you save her tears in the future.
we all wish we could do that, no matter how small or big the problem is.
I don't know if twisting this until it fits helps or not, but try. I hope you find a way to feel peaceful about it.
my dad died 4 years ago and all I have after him is his/my guitar I learned to play on.
I'm glad I have at least that, because loads of other stuff will never be accessible to me. things like family photos (especially when he was a baby or a little boy) my grandma's Bible, books, little cuckoo clock I'd love to have etc
it hurts like hell, but I just try to be grateful for being able to have this one thing he loved a lot.
I know you can't even give one thing you had as a child but giving her things,shared activities, lovely memories will make up for it, I promise!
(big hug)
