NBKSC 
We are a member of the Nederlandse Beroepsvereniging voor Kinderslaapcoaches (NBKSC). This is the Dutch federation for Gentle Sleep Coaches in The Netherlands. Karolien and Geertje are initiators and co-founders. Karolien is the chairman and Geertje the secretary. The aim of the NBKSC is to unite certified Gentle Sleep Coaches (GSC’s) in the Netherlands, to maintain the quality of sleep coaching according to the GSC method.
Network
We value working with other experts so that we can help families in the best possible way. That is why we have built up a network with, among others, lactation consultants, ENT doctors and general practitioners.
We also contribute to articles about sleep for 24baby.nl and Ouders van Nu. See here our expert page from 24baby. Click here for Karoliens and Geertjes profile of Ouder van Nu.
