Managing child-related expenses in Spain

Moving to Spain with children w/o a doubt is a challenge. Nonetheless, if you're planning to bring your children I strongly recommend coming alone settling in, and then looking for a suitable school close to your location (e.g. if you land in January, make arrangements so your children can start the following academic term or following fall, note there's no summer school here). Public education in Spain is free and parents only have to pay for meal plans and in some cases for books, there are also public nurseries where parents have to pay but they're far cheaper than private ones and to get a slot you MUST plan way in advance. Must say that public education in Madrid works quite well, don't know about the rest of the cities. You may enroll your kid in subsidized schools (known as concertados) or in full-fledged private schools that could run for a bundle of money. Even if your kids do not have proper documentation (e.g. residence card) they WILL be admitted to public schooling. If you have a disabled or mentally challenged child, make sure to bring ALL documentation to expedite paperwork - they take this matter quite seriously.

Probably you'll need insurance during the first year, but once the residence card is in place, with a secured job, public health should be available.

If you're planning to move in with an insurance plan, private school, and the whole nine yards it'll be no different than any other location in the Northern Hemisphere - the sky is the limit.
