Help how much bicarbonate soda in bath for toddler

[Foreverhopeful22]

Toddler has chicken pox. Bad in her genital area and I mean bad!!!!

I have bicarbonate soda for bath but how much do I use and how often. It's going in a toddler sized bath (bigger than a baby bath) but smaller than an adult bath.

Any other sugesdtions would be a godsend

I'm doing piriton and aqueous calamine cream

Good old calamine lotion every time.

I just chucked half the tub into a standard bath.
Oat baths are supposed to be good to (put oats in old tights or socks, secure end, and run bath with sock in it. Squish sock to get out more oaty fluid.

Half to one cup for a normal sized bath so perhaps stick to half for toddler size. Dd just getting over chickenpox and I found oat baths really helped the itching, I used Aveeno and she had long 3 baths a day at the worst point. Poxclin mousse was also brilliant but a bit pricey compared to calamine. However it isn't smelly, greasy, sticky and is really easily applied.
