Breastfed for 12 months but the last month I had to supplement. Baby went through all my freezer supply and now when trying to transition to milk she became so constipated. I was giving her organic horizon whole milk lactose free because I thought it would be easy on her stomach. Also tried fairlife whole milk which is lactose free as well.

Pediatrician suggested almond milk but she doesn’t like it.

Any advice would be greatly appreciated.

Also I wanted to keep her on toddler formula “baby’s only” lactose relief but the pediatrician said that toddler mills have too much sugar and I stopped but it was the only thing she enjoyed after not having enough breast milk. Wish I could’ve gone longer but I just started to dry up in the last month.
