This is a harder Q! I don't 100% know but two things give me hope.
First, there are so many incredible experts in early childhood right now that - IMO - are undervalued. We have so many that want to have a home to use their skills in support of parents alongside whatever they currently do.
Second, we're investing heavily in the selection and then ongoing support and / professional development of our coaches.
Over time we will need to increase the support and development even further but for the foreseeable future we're just happy how many incredible people are out there.
