My five day old DS2 has developed little pus filled blisters in the fat folds of his neck and thigh creases, they look a bit sore but he isn't acting like they bother him (sleeping and eating well, little periods of calm alertness). The midwife said to just keep and eye on them and our GP said no need to bring him down but I'm a little worried its a yeast infection or something. Anyone experienced this? Thanks..
