My 4 1/2 month old baby has skin rash that are watery?

Hello there. I have a 4 1/2 month baby who has skin rash that are watery.. I asked his peds regarding these rashes and she prescribed vaseline. But vaseline doesnt seem to be working for him. His rash on his righ cheek is a wound-like and it bleeds.. What ointment should I use...?

I have used Vaseline
Desitin
Virgin coconut oil

but nothing worked...... PLEASE HELP.....

thanks.

Don't put any ointment on it - you don't know what is causing it, and if there is an infection, you could seal it in. Go to a pediatrition and have the blisters diagnosed. If it is infact dry skin, you could put something on it. Ulcerated blisters are not normal for any baby your sons age. See a doctor right away!

Is it on his butt cheek (diaper rash?) or face cheek? This information would be helpful.
