DS "brushes" my hair with duplo and picks hats for him to wear and me to wear. If I wear a hat then hats are OK: if I don't wear a hat then he will take his off. DS loves "dressing" my hair and will spend ages styling it. But doing that means I can do ANYTHING to his hair and he has to be OK with it or I won't play hair salons.

Hair washing is still an issue but tough, he can scream and taste the lovely lavender and dill shampoo.
