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.

Click on each leap to learn more about what your baby is experiencing, how you can support their development, and what new skills to look forward to.
