Infant Oral Thrush, sometimes just called "thrush", is an infection caused by the Candida bacteria, which is a more common  yeast infection.

One of the most common symptoms in infant oral thrush is white patches found inside the mouth and on the tongue. This looks like cottage cheese or milk curds, and is sometimes mistaken for leftover formula or breast milk. These patches stick to the inside of the mouth and cannot be easily wiped away. In severe cases, when they are rubbed, the patches may even bleed. When an infant is nursing, and spits up, a mother might mistake this for the infant "throwing up blood", or mistake it for bleeding nipples. Gently wiping the mouth with a very soft moistened cloth will make it easier to see if thrush is evident.  

If your infant seems to have difficulty swallowing, eating, and is spitting up often, this could indicate a sore mouth and tongue. Check to see if there are sores or the white pasty film in their mouth.  

Because it is difficult to drink and swallow, your infant may have a poor appetite. This can be mistaken for lack of hunger or poor milk supply. With Infant Oral Thrush, your baby may act fussy, or cry.  

Diaper rash may develop due to the presence of the Candida that causes, Infant Oral Thrush. If severe, there may be sores on the infant's buttocks, sometimes blistering. Ordinary diaper cremes may not relieve these symptoms of Infant Oral Thrush, and more extreme measures must be taken.
