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

It depends on your LO. If your child is able to tolerate cow's milk, you don't have to go into goat's milk. As for my toddler who is a fully breastfed baby, he refused all types of formula powder. I had to give him full fat fresh milk. Usually bedtime milk i will warm the milk for him to drink. Day time i will just give him cold milk.
