Alternative “milks” sweetened vs unsweetened

Maya

Hey my babe is allergic to dairy and soy so I’ll be giving her other milks. I’ve seen ladies saying their doc told them to use unsweetened milks, does anyone know why?

I compared coconut milk to the homo milk recommended here and the sweetened original version still had less calories, less sugars and less carbs in general than the dairy milk, so why go unsweetened?

We already had her 12 month check up and I didn’t think to ask this question.
