Hola! I’ve just checked out the Weleda Baby Calendula Shampoo and Body Wash. The full set of ingredients are listed below. The good news is there is nothing offensive in this. It’s SLS free, does not contain any questionable preservatives, low in strong essential oils, 100% natural ingredients and 53% of them are organic. So should be ideal for your 2 year old.
