Your kitty is probably uncertain still exactly who this 'new' person is in the house. I'm assuming your girl is spayed - if not, that is one thing I would take care of very soon. You can try putting a couple of Feliway Plugins in the house - they can be purchased at most pet supply stores and contain phermones that are very soothing to cats even tho they are odorless to humans.
This is probably going to be a situation you will have to monitor until your baby is of an age where you can work with her to turn your kitty into her friend. I imagine with your daughter being small and down on the floor, this is disturbing to your cat as she has never had to deal with this situation before. I would also purchase a squirt gun or spray bottle so that if your kitty starts swatting or acting inappopriately, you can simply give her a quick squirt. This usually helps with inappropriate behavior very quickly. I would not let her actually see you do it. Just the feel of getting wet and not knowing where the water comes from will most likely deter the problem.
Please let me know if I can assist further.
