Instructions to convert to baby size:

CO 64 instead of 96. Do the ‘fitted’ size option. Omit round 20 of final crown decrease and then stop after round 21, omit last 2 rounds, so that you end with 16 stitches just like adult size. Crown will be pointy if you decrease beyond 16 sts. Fits perfectly on 40cm head with room to grow after blocking.
