I have a 4-month-old baby who has been putting everything in his mouth and drooling profusely. I suspect that he may be teething and is experiencing some discomfort. However, despite buying him several teething toys, he refuses to chew on them or show any interest in them at all. I'm worried that he will continue to feel discomfort and I'm not sure what alternatives I can offer him. I would appreciate any suggestions or tips from other parents who have experienced similar situations. Thank you in advance!
