My son cut his first tooth at 4 months old...I am a fan of tylenol however I would use the infant tylenol as needed but would probably try not to use it long term and/or consistently..maybe you could back off some though and use a topical like baby orajel? Teething can go on for a long time, so I'd save the tylenol for times when she is miserable and can't seem to get relief any other way. Right when the tooth is about to break through the gum...I gave the gel teething rings, ice cold wash cloth to chew on, massaged the cheeks along the jaw bones, etc..even at night b/c you know with everything the nightime is the WORST for it all. How old is your baby? Could she be waking from something else? Babies tend to wake a lot as you know...when you don't give it to her and she wakes, can you comfort her and get her back to sleep? Singing, swaddling, rocking, etc (see the above)? If so then I'd keep doing all that. I am not anti meds though, whatever it takes! LOL! I just try to use them sparingly and only when necessary. I don't think you will addict your baby to tyelonol or cause liver damage though. As long as you are dosing correctly and using the right product. Definitley a good question for the doctors though, if you have a good one they will be a great resource!!
