Spitting with a feeding is a common occurrence in prematures. It is usually only a small amount. Vomiting is a continuous throwing up of large quantities of food or liquid, and occurs other than at feedings.
Normal consistency is soft with some form or mushy.
Some babies may have a bowel movement with every feeding and others may have one once every day or two. Call your doctor. Honey is NOT recommended for infants under 1 year of age. Breast fed babies may not have bowel movements every day. If your baby has frequent watery liquid stools in 6-8 hours time or seems to have looser stools more often than regular, your doctor should be called.
