My granddaughter is coming to LM on Feb 16 and has this to say about her passport ... does anyone have the definitive answer?

My passport expires almost 2 months after my trip (April 19). Do you know if that is good enough for travel? Some things I’ve read are saying it must be valid for 6 months after the trip and some say for Mexico it just has to be valid for the trip. I talked with the passport people and they redirected me to the consulate general of Mexico but they aren’t taking calls.
