Any breastfeeding mums changed to cows milk or do bit of both?

My little one is 1 only feeds in morning and before bed but then 2-5 times on a bad night a night.

I was debating to give her some cows milk as like a afternoon snack to get more milk dairy in her? Anyone do this? She refused boob other then those 2 times and sometimes it has to be a dream feed to even get it in her

Expressed milk in beaker shes nkt interested in and even I express hardly anything comes out!

She also has never had a bottle so didn't know if to try some in a bottle or beaker
