How much BF milk for 15mo

[DD2017]

Exactly that... can anyone tell me how much breast milk a 15 month old needs to benefit from it?
I've tried googling but can't seem to find much information on it

As much or as little as you both like. Breastmilk forms a part of a balanced diet for a toddler. There isn’t a need to measure how much the toddler takes.

Any breast milk is beneficial as a source of calcium and healthy fats for toddlers.
