It is very difficult to be sure about your baby's rash without being able to see her. From your description it is possible that she has a rash known as papular urticaria. This rash is usually due to insect bites, especially due to the sand flea. A single bite causes all the pimples to appear and these pimples can last for months at a time. You can apply calamine lotion to the bites which are usually very itchy. It will also help to give her a small dose of a safe antihistamine such as Allecet Syrup 2.5ml once daily for 10 to 14 days. Giving her a good multivitamin syrup that also contains Vitamin B1 will help as well. If you have animals in the house make sure that they do not carry fleas.
