ive lived in santa fe for 3 years now, and childcare here can be hard and expencive. there is an organization called birthng tree cooperative (they mostly do prenatal classes and that kind of stuff), they have a meetup called many mothers circle, its every first wedn of every month at 10 am at santa fe soul (off of rodeo rd). they mostly have kids until 1 yo, so we dont go there anymore (plus, i work on wedn) now that my son is over 1 y, but i remember they were discussing creating childcare swap thing...if you pm me your email, i can send you their latest newsletter, there was sth in it about it.
also, if you go to meetup.com, there's a group of santa fe moms that do playdates and that kind of stuff. i havent done it yet myself,but planning to.
there is a lady in Eldorado that i know of that has 4 or 5 kids that she takes care of and i think its about 35 dollars a day, but i dont know if Eldorado will work for you because of the distance.
Community college has one of the best affordable childcares in santa fe, but i think there is a waiting list.
