You're all being a bit hard on OP... She's asking for advice because she wants to do the right thing!
The info about rabbit housing is great - the bigger the better, secure from bunnies digging out/predators getting in and either indoors or outdoors. Standard pet shop cages and runs are certainly not good enough.
But. Rabbits can make wonderful family pets, and it does them a huge disservice to suggest that they don't mix with children. We've had rabbits since before our children came along so our DC have always been around rabbits. They know to treat them with respect and care. Our rabbits dash up to our DC in the garden for fuss and are happy to be picked up and carried by them. Our younger rabbit will freely hop over 'jumps' that my DD sets up for her. My DC get so much from them.
My 6yo DD still cries at night sometimes because she misses our old bunny who died aged 12 over a year ago. They had a strong bond.
Bunnies can make great pets OP, but they do needs loads of space and you need to spend loads of time with them if you want them to be tame.
They need to be kept in pairs, neutered and vaccinated. Ideally get a pair from a rescue centre not a breeder or pet shop, although this isn't always easy.
