Hi welcome to BB 
My advice is to read up a lot on rabbit diets, health care, living areas, ect. Rabbits are so different from other animals and a lot of people think they are more like hamsters or other rodents (rabbits aren’t rodents). Also I would highly suggest that you get your rabbit spayed when she’s 6 months old, unspayed rabbits have an 80-85% chance of developing uterine cancer at an early age and spaying rabbits generally helps with their behavior, they’re more likely to make better companions. Also, try not to pick up your rabbit unless it is absolutely necessary. Most rabbits hate being held, even if they appear to be enjoying it, they think they’re about to be eaten. It can really cause distrust and an “unfriendly” rabbit, also can be dangerous. Your bunny will enjoy pets and attention from your kids when she’s on the ground feeling safe.
Binky Bunny has a lot of great info, especially if you have questions. Also House Rabbit Society (rabbit.org) is great. Good luck!
