Shaving cream works

I just put dawn dish soap on any stains and it always comes out.

I use Dreft. And whenever possible, after a stain I'll take off my daughters onesie or outfit, put a little of the detergent on the stain rub the stain with the detergent then use hot water and scrub the fabric together and the stain usually comes out or lightens up enough so that when I wash it, the stain is practically gone! This method usually works with any detergent, the key is HOT water and to catch the stain as soon as possible.

I make a gritty paste of dawn dish soap with oxyclean.( if the clothes are white they have a white revive or if they're colored they have versitile stain remover) scrub the paste on the stains and then mix dawn, oxyclean, and water in your sink or a bowl and soak the clothes in that for a few hours or until you go to do your baby's laundry. then just rinse and ring out the clothes and wash them like you would usually do. works on your own clothes too! I got a butter grease stain out of a white shirt doing this!
