Question: how often should my 1 month old spit up?
Answer: Some babies spit up more when they are teething, starting to crawl, or starting solid foods. A few statistics (for all babies, not just breastfed babies): Spitting up usually occurs right after baby eats, but it may also occur 1-2 hours after a feeding. Half of all 0-3 month old babies spit up at least once per day.
