Small blisters on my child's face

My son is 4 yrs old and was born with one tiny dot on his forehead. Dr's said don't worry mom it will go away a year later he had 2 dots on his forehead the size if pin heads. The dr's again said not to worry. Well needless to say he is 4 yrs old now and has 8 blister looking things in the middle of his head. I don't know what they are but these damn dr's down here don't help the matter. Hopefully on this site we could both get some answers.
So if anyone has any idea please respond.

my now six year old had some bumps on his forehead that looked like little liquid filled blisters as well, same color as his skin, hard to the touch. they spread to some other parts of his body; trunk, legs, arms. dr. diagnosed these bumps as molluscum (sp?) contagiosum...maybe your children might have it...could also be a mild form of eczema, acne (yes they can get mild cases) or another type of rash

My son is 4 now and I noticed these bumps when he was around 2. He had just a few on his chin just under his lip. They are very small and light in color (skin color). I had taken him to a couple of different dr's and the same as everyone else on here-I hear "oh it's nothing,they will go away" or "he may have an allergy to something". Well I'm extremely confused because they have spread to other parts of his body. He has one on his leg behind his knee and it has gotten bigger. He has one on his index finger and a few on his arms. The ones on his chin occasionally seem to clear up and come right back??!I know this is not normal nor contagious because I have another son and he doesn't have them nor do my husband or I. I am more concerned that it could be a sign of something serious. I hope it's not a sign of an illness or infection,but I am clueless as to why he has them and I don't want them to keep spreading.
I don't want to say I was happy to see someone has the same problem,but it's nice to know you are not alone or crazy-the dr's are good at making you feel that way sometimes!I'm sure if the dr's knew how concerned we were and took the time to look into questions that we have they might be able to help! Hopefully out of us all -one of us might get the answer we are looking for.

do they look like this?

Just wanted to say that my two year old daughter had the same thing and it lasted for nearly two and a half years. They look like tiny blisters and come and go mostly on the face but also on the limbs and trunk of the body. After seeing several doctors I was told that it was a type of wart, most people have immunities to it (so it doesn't spread to adults at all and rarely to other children) and there's nothing they can do to remove them without leaving scars. Luckily they have a life span of no more than three years. My daughter no longer has them, they just disappeared one day and didn't come back so if that's what your children have too than you should almost be done!

I HAVE THE CURE -
My son had these bumps (molluscum) concentrated heavily around his chin and eye and they spread all over his face and neck and to his chest. They spread from opening of the lesions when scratching or rubbing. Don't share towels or washcloths. Use a clean washcloth every time you clean your child after messes or eating and put it in the soiled laundry after use. Treat the infected area with 10% benzoyl peroxide (acne) cream or gel, twice a day. Any cream will work, I used zapzit (sp). Be careful when applying around eyes and mouth. You should see results within 7-10 days. Once the lesions are gone, they are no longer infectious as the virus lives in the skin. Stubborn bumps or those under clothing can be treated by covering them with tape until they disappear due to suffocation. Nexcare 3M (tan colored waterproof) tape works the best.
