My tiny little 2 month old has been cranky and drooly and chewing her hand or anything near her mouth for 2 days now! She was chomping my shoulder when I was holding her before. It isn’t that she’s extra hungry or anything like that…and she’s never drooled before. She has also been sniffley these 2 days. Any ideas? These seem like signs of teething but she’s too young right??
My OH told me that he was teething at 2 months 
Yes, that sounds like teething. It can occur at any age (some babies are born with teeth!) but is most common in babies aged 16 weeks +.
