Understanding Mental Leaps
Each developmental leap represents a time when your baby's brain suddenly has the ability to perceive things it couldn't before. These new perceptions lead to new abilities and skills.
During leaps, babies often become more fussy, clingy, and may have disrupted sleep patterns. This is normal and temporary - it's a sign that your baby is processing new information and developing.
