Hi, these are my first tries for the creation of your logo: #24 a mother which body creates a heart shape, is holding her baby, her hair are realized by leafs to give the sensation of natural and sage (as trees can be very long-living and can be compared with something sage).
#25 is a family, mother and father create a heart shape together, they both hold the child.
#26 an adult bringing a kid ont it's shoulders (making the kid "grow")
If you wish to have any change or you have any suggestions don't hesitate to contact me. Best regards
