You're doing great w/ her and bravo for homecooking! Cheese is fine in moderation - one thing I do is buy the canned parmesan and sprinkle it on their meat - they LOVE it.
What you do need to do when homecooking is use a multi-vit (which you are) and a calcium supplement.
I use Solid Gold's Bone Meal for calcium. I found this AMAZING multi vit/mineral that also has probiotics, digestive enzymes (bc those are lost by cooking the meat), and the Omegas - so it covers everything recommended for homecooking. Check it out here:
