I agree, bring as much as you can.
Not only are things two to three times the price here, but having more than one type of any item on the shelves is seen as inefficient and economically wasteful. Case in point for me was the bouncy chair I bought my Bub. We looked everywhere, and the only ones available were either Baby Bjorn or one other very expensive marque. Cost around CHF 85, built like brick sh*t houses and ugly as sin. The manufacturers probably had to convince the inspecting authorities that they would survive a nuclear strike.
Got one from Amazon UK, cost equivalent CHF 30, Bub delighted with it, and has christened it with a variety of different fluids.

Cheers
