This is not a strange question. It's a very hard decision to make when the time comes.
Everyone has to do what feels right to them. We had our first two cremated and kept their ashes here at home. When the time came recently to say farewell to a third baby, we knew we had to stop this "collection" as it no longer felt right to us.
Here is the thread I posted on the beautiful but sad day when we set our babies free.
I found peace with this and have revisited the site with my living babies.
