With our version of EHK, skipping a bath means misery - itchy, dry skin, flaking, and a keratin/bacteria smell. Nathan (3) usually starts scratching himself until he bleeds.
On the other hand, the days when we skip a bath means that the next day's bath is REALLY productive in getting excess skin off.
We have ichthyosis-en-confetti. It's a full-body EHK that doesn't blister except in infants.
Ichthyosis-en-Confetti Type 2
Husband, Nathan - 10, Elliot - 7, Oliver - 4, all affected.
I also have an unaffected daughter, age 8.
