How long can I keep feeding Similac Advance Step 1?

[Liesje]

I just started mostly breastfeeding because I'm taking domperidone and seem to have a stockpile of this stuff left: https://similac.ca/en/products/similac_advance_step1_omega3_omega6/
In all formats, ready to feed, bottles, cans, powders, all of it!
I noticed there is a 6mos+ formula as well, but how long can I use this stuff? I may have a lifetime supply on my hands here.

I'm pretty sure you can use Step 1 formula until they are a year old

I was told by the doctor that you dont need to switch to step two formula its more of a marketing thing so they can jack up the price... But with that said I would ask your doctor for their input.
