If you have animals in the home it could be fleas or mites. Are you sure they are bug bites. If she has other allergies this could be related. It could be a contact dermatitis. She may have come in contact with something she is sensitive to. I would take her to the doctor to make sure.
This is a case ruling out the most probable causes until you find an answer.
1. do you have animals? even if you have new bedding the animals can bring in fleas. etc. that love the carpet where a baby might be spending part of her time. 2. check your washer soap to see if it has any perfumes or gritty surfactants why? because some allergic responses can look just like bug bites. If you are washing the sheets and clothes in a soap that is not hypo-allergenic the baby will spend full contact with it for hours. Since you already know that she has allergies that heightens the chances of a reaction. 3. Is she sweating while sleeping? many mattresses that are setup for those with allergies have plastic covers just under the sheet, so if they start to sweat for periods of time they can also develop a rash that looks like bug bites. There are other things to check but start here and if these do not pan out let me know and I will give you the next set of possibilities.
I hope this helps...
