The difference between having a kid in diapers and one not in diapers is pretty big. Diapers are a pain in the ass (sometimes literally) and generate a lot of garbage, but there is also a certain amount of freedom that accompanies wrapping your kid in an absorbent layer. Often they will let you know when that layer is pushing its capacity, but the urgency in dealing with the situation is usually not ridiculous.
Once potty trained, everything changes. I should say that I couldn't be happier to be free of diapers and the associated paraphernalia that comes with having to extricate one's offspring from a saturated layer of human waste. However, now the dreaded cry of "PEE PEE!!!!" (or worse) has taken on a new threat level. In the car, this means find the nearest bathroom, even if you would previously never have considered using that particular facility. I have spent more time in public restrooms in the last few months than the previous two years, and I can tell you that not all are created equal. Generally the Wee One is pretty good about holding it together, but that doesn't mean that I'm not taking a mental inventory of every available bathroom in my vicinity at all times, in case.
The same principal is true for bedtime as well. Too much liquid before bed and we end up with the situation we had this morning at 5:00am. Imagine not waking up to an alarm with familiar music, but instead to the crackly screams of "PEE PEE COMING!!!" through the monitor a room away. Never prior have I needed the ability to transition from REM sleep to a full sprint in a second's time quite like the past few months.
I'm sure this will improve soon, but for the moment it's hard not to feel like a hostage to another person's bladder.
