Okay, I think a couple (well, several) things about daycares. One thing you need to understand is that the larger chains, like Kindercare and Tutortime, are franchised, and even though corporate looks over their shoulders, much of the day to day operations are left in the owners hands. So they will all be slightly different, and unless you can verify that the experiences other people have had are directly related to your particular facility, it's not entirely relatable, kwim? But daycare pay rates are low all over in my experience, and you'll find some teachers that don't mind that and others that do. I personally think it stinks...
That said, my ds went to Kindercare as an infant and I liked it. I did not think that the teacher in the 1 year old room was particularly dynamic however, and I didn't like her assistant at all so we left and sent him to Tutortime. We added our dd in the following year. ds did very very well there. dd was fine as an infant and had terrible troubles as a one year old and we left last September. The turnover was skyrocketing and things were bad. We took one of their employees with us (with the blessing of the director) and hired her as our nanny with a hefty raise. Turns out the pay did nothing for her motivation and her skills dropped considerably after she began working for us.
: So we're headed back to center-based daycare next school year.
Another question to ask is how many employees the center you choose has on exemption. For example, at Tutortime, they had two employees on exemptions for parking tickets. The offense, of course, would determine your comfort level.
I also wanted to comment on the partying thing. I used to party down, but I was still nice to kids during the day--I didn't work at a daycare, but I babysat plenty of kids, and I don't necessarily think that smoking pot makes you a bad caregiver, as long as you aren't stoned out of your mind while you're watching said children. On the other hand, if you don't get enough sleep, for me personally anyway, that interferes significantly with how well I manage my emotions and how much my abilities drop, so that's a different story...then again, I notice that the most since I've been totally clean and have had children, so even though I'm not high, I'm not necessarily the best person to leave kids with on a day after dd hasn't slept all night, kwim?
Good luck. It's never an easy decision, and it always feels like the lesser of two evils to me.
