  GT-shadows are tantalizing objects that can be thought of as approximations
of elements of the mysterious Grothendieck-Teichmueller group $\widehat{GT}$
introduced by V. Drinfeld in 1990. GT-shadows form a groupoid GTSh whose
objects are finite index subgroups of the pure braid group PB_4, that are
normal in B_4. The goal of this paper is to describe the action of GT-shadows
on Grothendieck's child's drawings and show that this action agrees with that
of $\widehat{GT}$. We discuss the hierarchy of orbits of child's drawings with
respect to the actions of GTSh, $\widehat{GT}$, and the absolute Galois group
G_Q of rationals. We prove that the monodromy group and the passport of a
child's drawing are invariant with respect to the action of the subgroupoid of
charming GT-shadows. We use the action of GT-shadows on child's drawings to
prove that every Abelian child's drawing admits a Belyi pair defined over
rationals. Finally, we describe selected examples of non-Abelian child's
drawings.
