L., our son was around 3 or 3 1/2 months when we noticed similar symptoms in him. He'd drool excessively and want to chew on anything in sight. I don't remember him having a slight fever, but he may have. Anyway, he continued to do this for awhile. At his four month doctor's visit, his pediatrician said that it could be teething, but that the symptoms can show up and occur for a LONG time before the teeth actually erupt. Well, our son surprised us by cutting his first tooth around 5 months (the average, according to a baby book I own, is 7 months). He wasn't really cranky with his teething until the night before the tooth broke through the gums. He screamed for awhile, and we ended up giving him Infant Tylenol because of his discomfort. The next day, we could feel the sharp little edge of his tooth. Then, he surprised us again by cutting another tooth just 10 days later. Now, at almost 8 months, he has two more teeth coming in (one came through just a couple days after the first; talk about crankiness, then!). So, it could be a possibility that your daughter's teeth are coming in, though she may actually show the symptoms of teething a long time before her teeth start to erupt. My book said it can be hereditary. If one or both parents got their teeth early, then the same could be true for their child. I hope that helps! Oh, and cold teething rings help, but Infant Tylenol really works if your baby just seems too uncomfortable. Good luck!
