Molluscum contagiosum?? They last for years!!! My niece had them - transferred to DD then DD transferred them on to DS. DD ended up with hers infected which cleared them up. Saw a dermatologist who suggests popping the bubbles with a needle through the side and then removing the core (a little squeeze and tweezers is needed) They do scar like chicken pox but they are fading on DD. For DS I am doing a few at a time and usually when he is asleep Just puncture the edge of the bubble with a preferably bigger injection needle. It doesn't really hurt but they don't like the look of the needle going through the side!!! Either squeeze or pull out the core or leave them to crust over and the core then comes out as it heals. They bleed lots when the core is removed so be warned!!

Although I would leave the nappy ones - they will go away eventually on their own but it can take a very long time. DD and DS had them on the trunk and under the arm on one side. DD had one on her face and DS has a few on his legs too.
