It is NEVER a good idea to offer unsolicited potty training advice, especially when your audience is a mother strung out from a long night with a breastmilk addict.
One “sage advice” drive-by at our local grocery store comes to mind. I was staring off into space in the dairy aisle when an older gentleman made his presence known. At least the encounter began friendly.
“How old is your son?”
With these kinds of questions, the response goes one of two ways…
I remember readying myself for his next move. Senior citizens love touching babies.
“Wow, nine months! That was the age that I potty trained my son!”
[Insert polite head nods and a weak smile here.]
I remember parting amicably after he began to discuss that same son’s “issues” in adulthood.
