I don't know if this will help you feel better or not but...A couple of years ago I had my younger daughter's passport in my hand while struggling to balance a stroller and a dish of food and an unhappy young traveller. Well, long story short the passport and the food had an unpleasant get together which left the passport wet, sticky and with a couple of pages that were very crumpled as they dried. I tried to get it replaced but they told me at the passport office that it was "minor" compared to what they had seen in the past and I should save my money and use it for the two more years that it was valid. Many trips later we've never ever had a problem. We've had lots of questions and lots of laughs from customs officers but no one that gave us any grief. Good luck.
