Parents, especially mothers, often worry when their baby wants to feed-feed-feed at the breast in the second week. Does it mean there's no milk? Is your baby the only baby in the world doing this? Are you creating a bad habit?
Be assured that this is normal behaviour. When your baby was born, he had a very tiny stomach, which was just right for the small amounts of colostrum (the first milk) he was getting at the start. By the end of the first week and into the second week, his stomach capacity has grown - a lot.
