So I am probably missing something obvious, but after setting up Family Sharing and adding my husband, I do not see any option to create an iTunes account for a child under 13 as part of Family Sharing. I can see the option to add additional family members and that just enables me to send an invite email to someone. I looked up how to do this and the info on the Apple site talks about there being an option "Create an Apple ID for a child" - I am just not seeing it anywhere. My iTunes account is fully set up with a working credo card. What on earth am I missing?
