Moving with a baby !!!

So I am currently trying to get out of a very bad situation and my husband supports me 100%. We are moving from hell hole
Kentucky to Colorado. I have done research, looked at the FBI database, looked at prices, etc for a total of 24 months now. But I want to hear from you. Where is a city that is not crime ridden and a good place to raise a 3 year old and a soon to be child? I'm thinking Littleton or Yuma or Dacono but I want to hear from you guys! How do you protect your home?
