I would strongly suggest picking up the "What to expect..." books. They have one for toddlers and I believe they have one for older children as well.
As for as teaching, I depend on a pre-school system for that. I do work outside of the home, so I made sure that they daycare facility I registered my sons in offered a structured program.
I do know that your children do not have to attend full-time daycare to register for pre-school. They have many facilities in the area. Just pick up the phone book and make some calls.
Health care is extremely important. My boys go to the physician once a year for a general physical/check-up. They visit the dentist every 6 months for routine preventive visits (cleaning, etc.).
It's a full-time job, I have three boys and we are constantly on the go. Between school, homework, sports, etc. I really don't understand how I hold a full-time job away from home, but in the end it all gets done.
Most importantly (and I am still learning this) DON'T SWEAT THE SMALL STUFF"!!!!
Good Luck and Congratulations!
