Since birth. I’m using cetaphil baby. What I did: Fill a small tub with water, pump a few drops of soap then either use washcloth or hands to wash baby’s hair. I will gently flip baby’s ears then either use a washcloth or shower head (low pressure) to wash off the soap and water. Shes 2.5yo now no issues with her ears.
I use newborn safe body and hair shampoos that doesn’t sting the eyes. I pump only a little bit, maybe a pea size, just for the hair. Gently rub the hair and rinse with water in my palm. Sometimes I pour water bit by bit. Go slowly until you gain confidence.
besides head to toe wash, i also use smth like this
use cloth
