It does slow in Summer. And it always does pick up mid-August for Sept starts. That not help with your concerns about solo child in July and August.

If you worried about that client's reaction to only being one child, then address it head on. This is time for you to consider who to reassure parent about that situation.

Think about things that only having one child give you freedom to do. Can you add day care cover to your car for these couple month only and if you can, would these parent be okay with child traveling in your car to field trips that when you have larger group, couldn't happen? Some parent totally against it but others might think this is great for a while - attention of a nanny for fees of group care.

Reassure parent that you are actively seeking new children but this is typically slow time of year as most do have summer care already arranged - then they know that this is short term situation only ..

Think about how and where you advertise. If you have passing traffic, put up a lawn sign. If your local bylaw not allow that, then get a car magnet and position your car on drive so passing traffic can see you have spaces. Can you put flyers in summer camp locations? Or in local play area, clay cafes, trampoline park - place where families go especially in summer time.

Use small group to your advantage and make sure any social media advertising mentions you are a small group to promote more individual attention.

What is unique about your dayhome? Do you offer something that other provider in your area don't? Maybe you screen free, maybe you provide meals which not common near you, maybe you are ECE qualified, maybe you used to be a Elementary School teacher, maybe you have large garden fully dedicated to daycare and your competition doesn't. There likely something different about your program if you think about it.
