Well just thought I would give an update. Ryan got a little worried at bathtime and tried to get out when Daddy got in but then we explained about the tipping his head back again and the shower and he sat there quietly and let my DH do it!! He had a great bath after that, he didn't want to shampoo his hair, DH did that, but he washed his face and body.
I am still thinking about the goggles though Nadia, great tip!
