Question for all the working mommas out there💁🏻

K.
I posted earlier about boosting my supply which I have been working very hard on. I'm going back to work and my stash is slim. I just wanted to have formula on hand in case my husband NEEDS it. I am EBF so this whole F word(formula) makes me cringe. But in case of an emergency or I get stuck at work one night I just want to have it on hand. I was wondering if there is any ORGANIC formula without soy out there. I was reading about goats milk formula also. Any advice??
