So how do you know if your child is getting enough vitamin d?

Question

my daughter has a soft spot and a crooked hip

Answer 1

If you formula feed your baby get enough vit D if you breast feed you may need to give baby vitamins or take them outside to get sunlight. An adult only needs to be in direct sunlight for 15 Min's to get the amount they need so a baby I would think would take about 5 Min's. But sunlight makes your body produce vitamin D so just take the baby outside and should be fine
