Responding quickly to baby's hunger cues starts the feeding relationship off on the right foot by making the infant feel that it can communicate its needs effectively. Babies spit up a lot - if weight is increasing adequately, this is generally not a concern. Fruit juice should not be given by bottle. By age 6-8 months, a small amount of diluted fruit juice can be given by cup. Babies should not have more than 3-4 ounces of juice per day.
Bottles are for breast milk, formula, and for older babies, water.
Colic - the infant has an immature digestive tract and GI upset is common. Also, gas can result from air swallowed during feedings, especially for newborns mastering suck and swallow coordination. Burping, proper latch on and holding baby in appropriate position during feeding can all be helpful. For severe symptoms, there are infant anti-gas drops. Pediatricians should be consulted if GI symptoms are severe, persistent, or if there is any blood in the stool.
