Baby Rash? Please help! Picture!?

It doesn't look like an allergy. It looks like petechiae which is blood like a small bruise. He could have ITP (idiopathic thrombocytopenia purpura), which essentially is unknown cause, low platelets causing bruising. Usually this resolves, also it can be vaccine induced. Call the doctor, its not usually serious, if he is lethargic and bruising alot then go into the ER. Check him all over before you call. They would probably want to look at it, and do some bloodwork.

You are doing the right thing taking him to the doctor. Are you sure the rash is only on his face? Good luck i hope it is nothing to worry about X

Has he had a fever? It could be related to that or an infection of some kind. Possibly an ear infection I would call the doctor ASAP

Call the doctor or maybe go in... Has he had shots recently, or any change in your laundry detergent?

Take the baby to the doctor.

Food allergy?

That looks so sad....good luck hope it's nothing to worry about.
