The silent problem.
Every day, your children shower and bathe in water loaded with chlorine, limescale and heavy metals. On fragile young skin, that water can dry it out, leave it tight and trigger the redness and itching that keep coming back.
You try the creams, the steroid cream, gentler washes. It calms for a few days, then the flare-ups return.
Because the problem was never their skin. It's your water.
