Hi S..
I have only used in-home or on campus after school childcare programs. I agree that one con is the possibility of an illness in the provider's home - or an emergency that might call away the caregiver - however both of the in-home care givers I used had back-up sitters to call...sometimes in the provider's home, sometimes in the back-up caregiver's home, and sometimes in my own home - depending on the situation/circumstances. So - I would suggest asking about back-up plans when you interview care givers.
Yes, a con can be only one person caring for your child (i.e. no supervision) but I can tell you from experience that all 3 of the in-home childcare's I used over a course of six years -in-home daycares are quite busy!!! Connect with the other parents - it can be reassuring to talk with them away from the caregiver...sharing information and such.
Con:
One sitter I used did not work on her kid's or City of Phx holidays (her husband's employer)...I however, sometimes had school (ASU) on those days and thus had to either find alternate care, use one of her back-ups, or take my kiddo to campus with me, if possible. Make sure you ask when you interview!!
There are so many pro's:
1) generally less costly
2) often can get 1-2 weeks of "vacation" pay
3) often are more flexible with, well flexible schedules. I have found that "public" facilities consider part-time as partial week, not partial day. This might not be an issue - but still a pro, in my opinion =)
4) many in-home caregivers will only take on 1-3 infants at a time...generally less in my experience, whereas "public" facilities have a room full of babies in cribs.
5) babies in swings, in play yards, on blankets - tend to get more attention at in-home care as they are more like family settings with older children interacting with the babes - babies don't get much social interaction with other kiddos in "public" settings.
6) often have better hours of operation
7) tend to work better with special diets/needs/medications, etc, etc
8) often also have pre-school and so younger children can participate (to their ability) in pre-school activities
9) in-home caregivers will at times take your child to activities - if that is something you approve of. Our first sitter took my son to her son's Little League practice - granted he was the only one to go but he enjoyed it!
10) in-home sitters can become part of the family - someone you and your child may come to love and see years after childcare is no longer needed.
Last - in my experience - I have found that in-home childcare providers tend to like kids...REALLY like kids. They would HAVE to love them if they are willing to turn their houses into a public space. I have also found most have decided to do this type of work not only because they enjoy being around children but that they want to provide a safe cost-effective environment for their own children. The "public" caregivers I have had personal contact with tend to be very young, very inexperienced, and work for very low pay. They may claim to love kids - but really, it is just a job to them...and many move on to better paying jobs (if they can land one). I personally would rather an experienced mom take care of my child than have him stuck in a baby room with an under paid, under experienced, and frankly under educated 18-20-something who "loves" kids. Our first sitter was finishing up her AA when we started - and recently her MEd - in child development and child psychology. She quit her business once her children were all school aged and now teaches in a school with special needs children. The other two were at least AA or BA/BS educated.
I can recommend one caregiver near Union Hills and 51st Ave if you are interested. I have no idea what her status is right now - we used her when we lived on that side of town before my son started K (2nd grade now).
Anyhow - you really need to interview potential providers and ask, ask, ask questions!!
I am hopeful this helps some. Good luck finding a provider!! =)
PS I know a mom who interviewed at Tutor Time on 7th St/McDowell a few months ago. She was there for 1/2 hour with the caregiver for the infants. The entire time they were there - a baby was crying from his/her crib - and not once did the caregiver check on the baby!!
