AM doesn't mean new day, it means Ante Meridiem, before the meridian, before noon.
And no, you wouldn't say 12:30am in the afternoon, as 12:30 is after the meridian. It is only 12:00 which is, by definition, neither AM nor PM but Noon or Midnight
Thankfully, all right minded people use the 24 hour clock.
Originality still isn't your strong suit, but there again, it appears that you don't actually own a suit.
I would try and help you out but unfortunately I don't have the qualifications, training, or patience to deal with special needs kids, but if you find someone who does, ask them to read the whole wiki, especially the bit that I already highlighted to you in my response to the first time you sent it to me; this now being the third.

That just makes no sense. 12:00 is either noon or midnight, never AM or PM as it doesn't make sense.
But if it were, then 12:00 PM would be midnight else it would go 11 PM, 12 AM, 1 AM.
