I have two toddlers, 2 and 3 years old, the past couple of weeks they have had these blistery bumps on the buttocks area. The bumps are filled with yellow puss and when popped they bleed a little and then there is a tiny hole left on the skin that will scab over. Both toddlers butt cheks are filled with these bumps. At first I thought it was a yeast infection because it started on my two year old who does get them when she has dairy, now my 3 year has them too and no cream or remedy seems to be working. I've tried neosporin, triple antibiotic, butt paste, vagisil, air drying, soap and water, etc. Any ideas as to what this could be???? My husband also has 2-3 bumps too, his are gone now. The babies have hundreds...
