If no, why not?
If yes, or if you have already, how often per week are they in care?
How do you feel about the service you get?
Having worked in the industry for several years, I wouldn't unless I had to. Mainly because I know what goes on during the day, which isn't generally bad, I just feel it isn't the best environment for children, especially if they're under 3 years old. I would send my child to preschool, for two days a week the year before they start school.
