Potty training

When I put my son down for a nap or to sleep at night he he's up and takes his diaper off and sleeps in his shirt only. Sometimes he doesn't mess and sometimes he does. Does this mean he wants to start using the potty like a big boy? Honestly I don't remember doing this with my daughter and it will be me only, daddy won't help. I personally think he'd learn a lot more from daddy in this department but I'll do my best. Any suggestions? Should I wait, is there a good time to start?
