Mum washed our hair every week. I intend to wash bubs hair with just water when they're a small bub...maybe when they get to the stage of being up and about, mushing food through it etc I'll do it once a week with a non chemical, natural shampoo.
KM, I think it's just cos bubs hair is so healthy on it's own Be careful with shampooing every night (especially if it's not a non-chemical natural shampoo) as it might end up irritating Miss K's scalp, especially as she has little hair lol.
