I never use the 5 and/or 7$ day care because I didn't want my kids go to that kind of "institution" too early, school come enought quickly. I didn't wanted that they were clusterized in group age for this period of life. I didn't want that my kids was "entertained" all the time. This was and is my choice, I live with it!
So I found a private day care place for dd1 when she was close to 2 years old (I didn't need it before because hubby was at home at that time). The year between dd2 and ds1 (so when I was pregnant of ds1), I had a woman coming to my home to take care of my 2 DDs. This was a good thing because I was also dealing with my dad's cancer at that time. But I hate to have someone in my thing, so after my maternity leave, we found a new private daycare.
At one point, I was having 3 kids in private daycare in the same time. Yup the bill was high, but it was for a short period... DD1 start the school, DS2 arrived no longer after and I decided to stay at home with my kids for an underterminated time.
So no more daycare private or at 7$ for my kids.
I think I have a problem with the principe of daycare... but this is me, other people could want or need it.
