At one year old, generally children can come off of infant formula. She can have finger food at this age and feed herself with her fingers/spoon. 4oz of milk is equal to 1/2 oz of cheese, or 1/2 cup of yogurt, or 1/4 cup cottage cheese. Here are some more suggestions to increase her calcium sources: Give her yogurt, yogurt smoothies (yogurt, fruit, and ice cream blended), all types of cheeses, ice cream, puddings, put cheese on her vegetables or make them with heavy cream sauce. Mix yogurt into her fruit and let her snack on cheese sticks. Make pasta and cheese or add cheese to rice and beans. Some children will accept whole milk if you add chocolate or strawberry flavor mix to it. Suggest giving her children chewable multi-vitamins, no need to crush up vitamins. Hoped this helped you.
She may be self screening foods that upset her stomach, my son is really allergic to dairy. He is 6 now and I am giving him a fruit smoothie now every morning with liquid childrens multivitamin, Udo's oil (Omega oils), dairy free calcium supplement, fruit juice, half a banana and a couple of strawberries. If she likes juice then she would likely take it easily and you can sneak alot of missing nutrients into a smoothie!
