Sounds gross... My 5mo DS has developed a small red spot under his neck. We thought it might be a teething related rash and have been careful to try and keep the area dry and change bibs often etc.
We took him to the gp after a few days and turns out its a fungal skin infection... Like heat rash/ athletes foot/ thrush type thing. We have s cream we're using that's meant to clear it.
Anyone experienced this? If so, did you have any issues with it spreading or coming back?
