Very cute, very easy once you get the hang of where the seams go, but at 9m i assume dc will spend at least some time on their feet so i'd go for something flat soled:
In English
Ch 10, dc in 2nd from hook and across, ch 1 turn (9sts)
Work dc rows for 3" (16 rows)
2dc, 2htc, tc, 2htc, 2dc across.
Dc around edge of sole. Sl st to join, ch 1.
Dc in back loop only around. Sl st ch 1. Finish off and restart in corner of heel. Change colour here if you like - i like to change to Sirdar Snowflake :)
3 rows of dc.
Mark centre of toe. Count 10 sts each side and mark. Dc around until you reach the first marker. dc3tog, dc2tog 7 times. Dc to end of row, sl st ch 1.
Mark centre. Count 7 sts each side and mark. Dc to first marker. Dc3tog 5 times. Dc to end of row, sl st ch 1
Dc around. Either finish here or carry on to get a cuff
Sorry if i've x posted, had to make one to pattern it!
If that's too small, just make the sole bigger and rejig how many decreases you do - might need a third row in a bigger size :)
