Hi all,My 3m 13days old son is sucking his fingers and hands, makes weird noises. He drools n dribbles too. At tyms presses both lips together and bites lower lip. While surfing on net I came to know it's teething sign so at times I give him teether. He's become cranky and sticks to me and sleeps less. My friend suggested to give Calcarea phosphorica homeopathic medicine.
