Northwest Denver and the Sloan's Lake Area are great neighborhoods but might be kind of pricey for rentals. Although, if you look hard enough you might find something cute and affordable. Public transportation runs just about everywhere in the city but North Denver is very close to downtown and it's easy to get anywhere from there. If you are low income, you might qualify for CCAP (state childcare assitance program) and they pay a good portion of the daycare expenses. You are only charged a low monthly fee. Under this program you can send your child to any day care center or in-home daycare provider that is licensed with the state. More info here: http://www.denverccap.org.

I have a 3 year old son who goes to preschool at A+ Kids in North Denver. They have a toddler room, preschool, and school aged classrooms. He loves it and so do I! My daughter is 7 months old and she goes to an in-home day care. I am actually on the waitlist for CCAP so I am paying full price right now but the care my children receive is definitely worth it. Anyway, good luck! Send me a message if you need any more info or would just like to chat :)
