My 7-month-old son has rash around his bottom with several little red bumps that looks very much like pimples filled with whitish liquid. Any mummies experienced this? Is this a different type of diaper rash? Any home remedies I can use?

i noticed the same with my younger one. in fact, i used to think its some sort of diaper rash, but turned out it was a sign of lactose intolerance. does your baby cry while pooping? or hold on poop for a long time? if yes, it could definitely be lactose intolerance, in which case you need to go to a doc soon. also, even if it is a diaper rash, i would suggest you immediately get it checked, especially as you mentioned it is filled with liquid, which definitely means some sort of infection. take care.
