Strange Planet by Nathan W. Pyle

Babies love deception.

It's when you tell them that you're not their real dad later on that the trouble starts.

Also: pants today, socks yesterday, these guys'll be fully clothed soon.

if you do this before they have Permanence, they think you have the power to create an entire person out of thin air.. it is only much later that they discover you are not a God.. the ultimate deception..
