Hello everyone! ? The baby is almost three months old, started spitting up and putting his little fist in his mouth, read that it's teeth. Especially before bedtime very excited, jiggles and puts his fist in his mouth. Are there any ointments, creams, pastes or medications to help? Did you have this situation? Ugh, I think only colic and gas went away... ??
