No, he's not a bad parent, he's just a parent.

When you have a kid you see them every day, you hear every complaint they make, and they make MANY. One or two specific complaints intermixed with the whinges of every day life are not generally actionable unless one notices performance degradation or other symptoms.

I (like Alicorn) have had headaches all my life ranging (in an almost power law graph) from very minor to severe. In the early years they usually manifested themselves as sinus related, and my mother (a health care professional) took what steps were available--in my case a humidifier as mostly the problems were during school (cold, dry weather). It's very rare I get a severe one, and in only one case has this required a trip to the emergency room.

Although for me NSAIDs never did a damn thing. They don't usually work (short term) on my aches and pains either--it's not until they start to work on the swelling that I get relief.
