Ok ladies I have a situation.

Ds is on ABs as he has tonsillitis. He's on the mend now but the ABs are giving him the most horrible runny poos ever and they have stained my TL wool cover, flat and a couple of boosters. Any idea how I can get it out? Needless to say we are is sposies and his poor little butt is so red raw, he cries when I wipe it
