Axel has been showing signs of teething since 5 months 3 weeks. I discovered white caps on the bottom in the middle and now two teeth emerging on that part.

 

Drooling and biting finger are part of the signs.

There are many teething rings brand to choose from and I purchased NUK brand since it is simple, soft plastic and not hard like the other brands. I chill that teether in the fridge before giving to him. He totally loves it! He chews every time after feeding or whenever he wants.
He is really concentrate chewing on it....
