Fall: Call for information and brochures; observe schools in which you're interested.
Late spring: Decide which school your child should attend; if needed, plan another visit.
Summer: If possible, point out the preschool to your child, and play at the playground.
You may worry that your child will fall behind if she doesn't get the "right" amount of preschool. But a few mornings a week is fine, especially for younger preschoolers. Sociable 4-year-olds may enjoy the routine of going to school five mornings a week, but they don't need to go to school every day to thrive in kindergarten.
