Teething – between 3 and 9 months, your infant's baby teeth will begin to erupt. Teething may make your child irritable or fussy and may cause restlessness, drooling or loss of appetite.

Pacifiers – sucking is a normal part of development that is comforting to children well into their first years of life. In fact, sucking often brings comfort even after a child no longer needs to get nourishment from a breast or bottle.

Baby bottle tooth decay – this occurs when acid formed by bacteria on the teeth, from sugars in foods and beverages, damages the tooth enamel. This causes demineralization, and eventually can lead to a cavity.
