" The Four-Month Fussies Your baby’s growing awareness has its temporary downside. At an LLL meeting a while back, a mother arrived with a four-month-old, saying he had begun “nursing funny.” Another mother in the room said, “My baby’s four months old, too, and she’s started nursing funny.” And another mother spoke up with the same age baby and same concern. We dubbed it the “Four-Month Fussies” but didn’t have a perfect solution for them beyond nursing in a quiet room, minimizing distractions, time, and nursing in whatever position the baby seemed to need. The group concluded that by around four months, babies had gained enough intellectual ability to tune in to the room around them but didn’t yet have enough gray matter to tune in and nurse well. "
