I use a cup, normally I wait till she stands up and looks up (she likes looking at the shower head) then I rinse her like that so I don't get any in her eyes.
I honestly just dump the water on my son's head with a cup
I use the handheld shower head and just run the water over her head and face. No point in letting her be afraid of water getting on her face. We've been doing this since she first started getting baths.
I use a cup. We have a light over the tub so to help him look up, I'll say "Where is the light?" Or "Look at the light!". I'm sure you could put stickers or someone else up high that would encourage her to tip her head back to look.
I literally have to hold her up like a dog under my arm and put her head under the water. Otherwise she’ll jump out of the tub trying to run lol
I use a cup but it’s for baby baths
