Thanks, everyone. I started making some inquiries and will follow up on some other ones listed here too.

If you're closer to the River Road/Mass side of Bethesda, Petals Child Care. The three year old class teacher is THE BEST. They have a 5 day and 3 day option + you can do before and after care there if you need it.

Bethesda Country Day has been great for us. They offer multiple flexible schedules and provide breakfast and lunch. Very warm environment.

If you are open to coops then Bannockburn Nursery has space in its 5 day 3 year old class. It's a lovely school.

If you are considering a preschool + daycare setting, I would also add Rock Spring Children's Center to your list. Pricey but so worth it! And I know that a few of my daughter's classmates in the 3-year-old classroom are leaving at the end of August.

Bethesda Reggio has a couple of spots in its preschool class for 3's this fall. We are located off East-West Highway between Connecticut and Wisconsin Avenues near B-CC High School. To schedule a visit, email us at Contact@BethesdaReggio.com or call 301-310-8008.

Hi there! Whole Kids Academy is a new language immersion preschool in Bethesda conveniently located on Old Georgetown Road between 495 and NIH. We are now enrolling children ages 2-5 for our September opening. If you would like to find out more please visit us at http://wholekidsacademy.com or give us a call at (240) 343-4952. Thanks!

The Bethesda Montessori School (corner of Arlington and Wilson) might have openings. DC1 went there and I have enrolled DC2 for the Fall. We are happy with it.

Directly opposite (on Wilson) there is a church co-op nursery school, with shaded playground (very important!).

Any leads would be much appreciated.
