We go to Glen Mar in Columbia but very close to Ellicott City and so far we really like it. They do a lot of cute activities with the kids even when they are really young - they fill up quickly, as do the ones on route 40 and the Montessori schools. I had to book daycare before telling most of my family I was pregnant to get a spot 12 weeks after delivery. Feel free to DM for more info and good luck! It is hard out there.

I actually found Geln Mar through the Locate Family Child Care network which is a good resource when you are looking after listening to an NPR story about the website: https://www.marylandfamilynetwork.org/for-parents/locate-child-care
