preschool-yes or no?
I think that preschool is a good idea, especially if you have 2-3 small kids in your house and you need some extra time for yourself. My son started his preschool at age 4, and I wish he could go at 3. His preschool schedule was 3 days a week for 2.5 hours. He played with other children, had fun learning stuff, and I was able to go to grocery store, doctor's apptt, or simply do something at home.
If you're not comfortable with an idea of preschool, or cannot find one good enough for your kid, you can try to find preschool curriculum online and teach your kids at home.
Did your toddler attend preschool and what can you say about his/her preschool experience?
