Most eczema is caused by allergy, and that being said usually caused by yeast (see above guy gets it worse when drinking), also the person that mentioned sweaty areas as it is not the sweat but the yeast bacteria thriving that is already on our skin, other forms of external yeast are atheletes foot/jock itch. Notice you said changing the little ones diaper, possibly added to a nailbed infection on you.

Also you might not think you have anything on your feet however usually it is not as bad so inspect your feet well for small bumps on the sides of toes.

For the above, get some tolnaftate cream (foot care aisle) and try it(on hands/feet/anywhere else you suspect, let it work in) before the steroid cream on your hands, soon as it is gone, or getting better cut the steroid cream WAY back as it weakens the bonds between the skin cells on your hands.

Another in my family has it extremely bad and one trigger is sweetnlow/sugar twin/saccharin.

The soaps usually do not cause it however they will cause inflammation from certain SLS amounts and certain perfumes.

My hands are pretty much my living (mechanic) so I have to watch them very carefully now, I have had this now for approx 23 years, most of my family have it as well :/

Good luck and let us know if anything works.
