My daughter will be 3 months old in 4 days and is teething terribly.. she is always chewing on my finger or her hands and screaming and crying all the time, this ear piercing painful scream and cry. Nothing calms her.. I try Tylenol but she just spits it out so I have to do drops at a time in the back of her cheeks.. she won't take any tethers.. MY before got his first tooth at 3 months too!! What helped best for your early teething baby, or your baby teething ?!
