Naturally you give the child the honour of her first kill, and both you and mother Sphinx play along as you fall over and let child ineffectually gnaw on your shin as you dramatically cry out about the indignity of you, an adventurer of 30 years, being bested at riddles by a child.
The mother dramatically then "finishes you off" (keeps you safe in her mouth and deposits you outside). You return a week later wearing a mustache and glasses, as discussed.
This becomes a regular thing, each time with a different costume, as you see the baby's confidence grow over time
