Preschool Yoga ages 2-5 thoughts? recs?

Hi everyone!

I currently work with kids through an enrichment program and am thinking about creating a mindfulness and yoga movement program for them!

I love yoga, although I am not a certified. Sometimes I feel a little imposter syndrome because I dont have yoga training. I attend classes and practice my own/videos at home. I did take a certified online kids yoga course and I've been working with small kids for 15 years. I want to help some of these kids find tools to get through their big emotions and build their confidence and resilience! To help them grow in the best way, showing them ways to regulate, etc. and showing them kittle bits of yoga through yoga adventures.

Is there a certification or program I can add to this? Any recommendations or ideas? What are your thoughts on me not being a yoga teacher and not taking the training?

Thanks so much for reading. :)
