Which is better for LO who is turning one and has been fully on breastmilk? Formula milk, goat milk or fresh milk?

Depending on what is more suitable for your toddler. You can give fresh milk or goats milk. I did both. The price per month is about the same. So I switch between both however if you can, better to give goats milk as it is the closest to breastmilk. I get mine from hay dairies.
