Anything that a kid of 2, 3, or 4 could learn at a preschool, they could also learn from there parents. With an added bonus of being able to spend a few extra years bonding with their parents before they have to start spending all day in school. What do you think they can learn in preschool that can't wait till kindergarten?? There's not much.
- The Alphabet?: You can easily teach your own kid the alphabet.... unless you don't know it yourself

- They don't need to know how to write much yet, but they can learn to speak just by watching you
- How To Count?: I think you can also teach them this
- How about colors, shapes, and other things like that?: You also know all about that stuff and they can learn that simply by watching you too, and playing with toys that also serve to help with teaching that stuff
We could keep going, but I think that anything you could come up with could be taught by you. Preschool is simply not necessary. Why would you want an excuse to be apart from your kids anyway? You only have a few years until they have to go to school. How do you want to spend them??
