My poor 3.5 month old is already getting teeth. She's still too little for holding a teething ring, so night time she gets very upset. I asked our Pedi and she recommended 20ml of Tempra drops before bed. Although it's been Dr. recommended, it still makes me a little nervous giving her them so frequently. I did give in last night after 3 hours of crying and gnawing on me. She slept really well once they kicked in. Any thoughts?
