I'm a parent. We're moving to the Netherlands next month. I just sent emails to the local taalschool in Hilversum (and two basisschools) to ensure that my daughters learn Dutch as fast as possible upon our arrival because learning the local language is critical for living a full life. Any parent who doesn't do this, except _perhaps_ for those who know they're on a short-term stint for work or similar, is being negligent.
