Little-known parenting fact No. 138: your child care situation should make you feel like a bad parent.
Not will; not could; but should.
Don't get me wrong. You should never find yourself wondering if today is the day your child's brain actually melts out from doing nothing but watching TV and going to WalMart for forty hours a week, nor should you be afraid to occasionally give them a treat on the weekend because you know they've eaten nothing but McDonald's and Nutella on white all week.
The ideal child care situation produces parental guilt for reasons entirely different:
... in short, because your child care provider is way better than you. That is the child care situation you seek.
Once you've given yourself a solid guilt trip over never having learned Russian - or, truthfully, much of anything useful, what was all that education business about anyways? - then maybe one or two more just for good measure and to get it out of your system, come talk to me.
Closer, Grasshoppah, let me whisper in your ear.
No, really. Someone else just did all the hard work for you. You paid them for just that purpose; your conscience is clear. Now you are free to chill out with your family and really enjoy your kids all weekend long. черт, maybe they'll even teach you some Russian.
