I don't know how far one can take Victorian sentimental poetry as a guide to child development, but I give you Charles Tennyson Turner's Letty's Globe:

When Letty had scarce pass'd her third glad year,
And her young, artless words began to flow,
One day we gave the child a colour'd sphere
Of the wide earth, that she might mark and know,
By tint and outline, all its sea and land.
She patted all the world; old empires peep'd
Between her baby fingers; her soft hand
Was welcome at all frontiers. How she leap'd, And laugh'd, and prattled in her world-wide bliss;
But when we turn'd her sweet unlearned eye
On our own isle, she raised a joyous cry,
'Oh! yes, I see it, Letty's home is there!'
And, while she hid all England with a kiss,
Bright over Europe fell her golden hair.
