They are all very very similar as they are so closely regulated and have to have very specific nutrients. Tbh, if it's the case of breastfeeding but having some on standby then I'd get some bottles of ready made, depending on the brand they come with teats too so all you have to do is open the bottle, open the teat and put it on! Given shops being open almost all hours you'd be able to get tubs of formula if you needed it. Kendamil is often very hard to get, I would pick a brand that is readily available in the supermarket you use most often. We just used Aldi formula when we did move to bottles and she had that until 18 months
I loved Hipp Organic with my first so will be going with that again this time.
Kendamil Organic is great. 100%
