These are my tips for being little in public which are for secret littles. 1: Skipping/hoping. I personally tend to be energetic at times and I skip for a short bit or hop. Especially when crossing a street, jump up onto the curb instead of normal walking.
2: Something else I do is awe at like anything cute or something I adore in my head.
3: My last one is smiling. Not sure what it is but I feel that smiling while in little space helps
I hope these help in some way. If you read this far thank you and if you want better tips how check out my fellow posters I am sure they can help ~😛
