Will Melcolm be Potty Train Soon?

Today MIL comment that Melcolm knows how to express himself when he wants to make "chocolate cake". She then brought him to the toilet and he poo there. At night while we're having dinner, Melcolm say "pass urine", then we brought him to the toilet and he "sh sh" there. It was also the 1st time he reached home without wearing any diaper today. Hope he will be potty train soon :)
