Any suggestions about daycare?

I have a 5 month old and so far I have stayed at home with him. I have recently been thinking about going back to work part time. I am a dental hygienist. I am not too sure about daycare. My child cries all of the time, and I am not sure how he would be treated at day care. Any suggestions and is it even worth going back to work to have to pay for daycare?

If it would take most of your check it really isn't worth it. That is one reason I stayed home. Another reason was because my son was a preemie, and too many parents try to sneak sick kids into daycare so they don't have to take the day off work. They don't care if they spread the sickness to other kids. Also, I would have missed so many milestones with my son if I had returned to work.
