Emergency formula??

L

Hello everyone! I am 14 weeks pregnant with twins. If everything goes the way I want, I plan to tandem breastfeed at home and pump to have an extra supply for bottles to use when out and about or to give me a break sometimes (and let my husband be more involved) especially at night. So fingers crossed, cause that’s a lot of milk!

My question is - do you all keep any formula around the house for emergencies - say you aren’t able to produce enough milk sometimes or something like that? Any favorite brands? I do live in Europe, so I can easily get European brands. I also have access to American brands through military bases here.
