Posseting or bringing out milk

 It is normal for babies to bring out some milk after feeding. In the early days, it is because of adjustment to feeding. Later it is usually due to overfeeding. Some babies don’t tolerate formula or cow’s milk but retain mother feed. If the baby is passing adequate urine and growing well, it is of no concern. If vomit contains bile or blood or if urine is reduced or growth is not adequate, it should be looked into ASAP. Some babies learn to bring up milk to enjoy the sour taste.
