This is a womens charity/shelter and although I have not donated anything myself there I believe they are always in need of clothings (children and woman, also pregnancy), toys, accessoires like car seat, pushcar, babybath, washing basin, pot etc. for our clients in need. http://www.muetterhilfe.ch/
