Track Over 400+ Developmental Milestones

Milestones take the guesswork out of parenting

Young children grow so fast that it can be hard to know what to expect. Tracking your child's developmental progress between well-child visits is an important part of monitoring their overall health and well-being. Knowing how your little one is progressing helps you identify if any areas of development may be lagging or if potential problems need to be addressed and discussed with your pediatrician.

of a child’s brain develops by age 5

At age 2 or 3, a healthy brain has up to 2X as many connections as it will have in adulthood. This makes it the perfect opportunity to help shape your baby's future success in both learning and life.

After 5 years, brain eliminates weak connections and strengthens the ones that are reinforced. This process is called pruning and it helps shape your child's brain architecture.
