This is normal at this age. It doesn't necessarily mean teething.
i have a 2-3 month old and he also started drooling and putting his hand in his mouth. This is normal, and they are not teething yet. Mine got extra fussy too but it was mostly due to wanting to nap.
Normal for that age, probably a cluster feeding period , it’ll end eventually x
My 2 month old is doing the exact same thing.... I really wanna know what people have to say about this. Is my LO just self soothing with her hand constantly in her 4 should we start teething remedies?
