Re: [where to buy] maternity/baby items Zurich area
Toys R US (probably one of the cheapest places) Spreitenbach and Deitlikon.
Mac Baby - Altstetten http://www.macbaby.ch/content/index.php
Baby Haus - Jona - http://www.kaenguruh.ch/ Best prices I found for trip-trap and Romer car seats.
There's a big baby place opposite Hornbach in Littau (but never tried it).
As mentioned before H&M has clothing, also Manor etc...
Try a few google and/or telephone directory searches too.
Re: [where to buy] maternity/baby items Zurich area
Depending on when you are due, I still have sweaters, dresses and blouses (Gap/ Old Navy/ C&A) that I'm looking to get rid of for cheap. Rather see someone get some use out of them then to bin them in the kleidersammel sack
