water alone usually does the trick for my little girl. and i make sure that i comb her hair while its soaking wet, to get out any food pieces that may need a bit of extra help.

the conditioners ive used on her have been giovanni, elucence, and currently california baby calming conditioner (i think im going to stick with the california baby).

and maybe you could wash your little ones hair with shampoo once a week and then co wash the other times. that way she gets her conditioning and clean hair without wwII!
