Hello! my son has this same "problem" and he is almost 19 months old. I just change him and leave the room. i try not to talk to him if possible so that he will go right back to sleep. they can't help when they go :) so just make the best of it, and both of you try to get some sleep! as he got older, it did get later in the morning, now it's not usually until 6:30 or 7 and he usually makes it until he gets up at 8. again, good luck!
