Tyler, your routine sounds a lot like my husband's and son's.
We have an EHK variant.
One thing that Brian does every 6 weeks or so is to use a hand-held power sander on his feet. He used to use a Swiss army knife to hack off the EHK callouses, but then I discovered the Dremel. [img]http://www.ichthyosis.com/ubb/smile.gif
To do it without burning yourself, it works best when fresh out of the shower. We put a chair in the shower stall and put a towel on the floor inside and outside the shower. He Dremels his feet, then folds up the towel and wraps it in the tower outside the shower so I can put it directly in the washer. In the meantime, he turns the water back on and rinses the dust off, then gets out and creams like usual.
Creams we use are Jergen's Ultra Healing and Cetaphil. There is also a melaleuca oil cream that we have tried and been successful with.
Brian and Nathan get VERY itchy if they miss their bath, even one day. Nathan has on 3 occasions so far reached into his diaper and scratched his back until it is bleeding.
Right after the bath (hour for Brian, abou 30-45m for Nathan, who is milder) their skin is very fragile. The lightest touch will take off layers - I can get extra skin off Nathan's face just by rubbing with the towel or my finger. It dries VERY quickly, so I have to get cream on it within 10 minutes or else get back into the shower and get him wet again.
The palms and soles are the worst - they get a lot of buildup and rubbing the skin doesn't take off the layers like it does on the arms, legs and back. I use a heavy-duty nail file (like the acrylic nail salons use) about every 3 days on Nathan's palms and soles. Brian does his hands every 2-3 days, and lets his feet go until it is Dremel time again.
We use the plastic wrap on Brian's feet in the evening for a couple hours so he can walk. He discovered that leaving it on all night makes them itch too much and makes them prone to growing mold or bacteria or something green.
For Nathan, I put Aquaphor under his toes and put regular socks on, then file them in the evening.
We do showers, not baths, because of the amount of skin that builds up in the tub clogs the drain and is nasty to clean. We soak for 10-20m, then come out of the water stream and rub the skin to whatever degree of success we have. Brian uses his hands and Safeguard soap to remove skin. I cannot use soap to get skin off either of them - I use my own skin oil to get a spot started, then I don't rinse the loose skin off until I am done. It gives me some friction. I soap at the last minute, then wash his hair with either baby soap or dandruff shampoo, depending on how many open sores he has. The baby comb takes the scales off his head pretty well.
We have tried the salt baths. It does nothing for us in both light or heavy concentrations. We have tried Tazorac. Nathan ended up with raw hands from 2 days use. It isn't worth it. Brian used to be on Retin-A. He decided it wasn't worth it because it would not penetrate the thick layers on his hands and feet, and took too much off the thinner areas.
For ears, Brian has folded a paper clip into a swab shape so he can scrape his ears. He follows up with a q-tip. I use just regular q-tips for Nathan, but it is only successful when he is wet. I have a Dr. Mom otoscope ($20 US from Ebay!) so I can check for buildup, and we have a standing appointment at an ENT if necessary. So far, we haven't needed it.
Wintertimes are worse for us, so we run humidifiers in both bedrooms. We also have a wax machine that works when the air is dry.
