DS is 5 1/2 months and is teething and lately having rough nights waking up clearly in pain from teething. He has not had a tooth break through yet. DH wants to give him tylenol before bed every night. Anyone else doing that? The past 3 nights he has slept all night and wakes up much happier. I just want to make sure I am not harming him giving him Tylenol every night.
