Rash on same spot both hands?

What could this be from?? I just had a baby if that helps any. My skin was extreeeemely dry from washing my hands constantly and then when I put lotion on I noticed this popped up. Is it just from dry skin or something else? Some pics of hand food and mouth look like this but others don’t and I don’t have the rash anywhere else. It also stings so idk. Please help
