Update a logo for a preschool nursery

Description

We have a logo already for our preschool nursery - www.singlestepsnurseries.com - but I've grown tired of it and want a refresh. This project is an evolution rather than a totally new logo design.
Attached is our current logo. The colours are to stay the same, please sample colours from the logos I provide so they remain exactly as they are now. The font to use for SINGLE STEPS NURSERIES is Crete Round. Our logo is used in many places, such as letterheads, email signatures, printed materials, website, embroidered on uniforms, signage, etc. etc.
The image is a print of my son's feet, I'd like this to replace the toys and other items in the current logo. Maybe the feet could be turned slightly so they make a sort of heart shape, not blatantly obvious but there if you know. Plus I've attached a screenshot of the versions I'll need once we have the final logo perfected. Thanks!
