I'm really sorry you lost your little girl, I lost our son Archie at 17 weeks too.
Firstly some practical advice. We have the same problem with rabbits eating Archies flowers, we've found they don't eat Sweet William, anything from a bulb so daffodils, tulips, crocus etc (although you can't get them now). They also don't eat any types of Lily, alstroemeria and a few other plants.

Some one also told me that if you spray the flowers with hairspray they don't eat them, but I've yet to do that as I usually buy ones they don't eat!
At first it upset me but now I try and think that Archie probably loves the rabbits visiting, DH was saying no to some flowers I wanted to buy the other week as he thought the rabbits would eat them, I told him Archie would be upset as we haven't fed the rabbits for a while, he must be missing them.
Big hugs, get in touch any time you want xxx
