I'm not sure we have any formula feeding mums from Germany here!
All formulas are pretty much of a muchness though as they are all made to a standard. What suits one isn't always the best for another so your best bet is to pick a brand and see how it goes! A formula suitable from birth is fine for the first year, there are 6month+ formulas available in the UK so you can probably get those. They tend to have more iron which can be constipating though.
