My middle Son Isaac was like this. He just hated the shower and would scream every time he had to have one. My other son hated showers or baths at other peoples places.. they both just stopped doing it one day

with Isaac we just got on with showering him and ignored the screaming. All the other attempts to calm him didn't work and just got me frustrated. so the quicker it was over the better. so basically we didn't acknowledge him when he carried on.

Has anything happened to her around water? With Isaac he fell into some water last year when we were on holidays and it scared him for ages.. Not so much of the shower but of pools infact he still won't get off the steps in the pool..
