Don’t miss a milestone first

It’s easy to miss a milestone the first time it appears because babies aren’t like clocks. 6 pm arrives at the same time of day for all clocks, but babies aren’t so consistent. The age when babies reach a particular milestone varies tremendously. Because babies reach milestones at very different ages, it’s easy to miss a milestone.

Start watching early

It’s exciting to see the very first appearance of a milestone.  If you don’t want to miss one, there’s a simple solution. Start watching before most babies reach the milestone. But when is that?

The Don’t Miss tool suggests start month for each milestone. Begin watching during that month. You’ll be unlikely to miss the milestone.

Things to remember

  • It’s unlikely that your baby will display the milestone in the month listed.
  • Most babies won’t reach that milestone for weeks or even months later.
  • Milestones in some cases are fleeting and easily missed.
  • Some milestones don’t appear at all.  For example, a few babies skip hands-and-knees crawling.

To see the detailed descriptions or each listed milestone, you’ll need a Catalog membership. If you choose not buy a Catalog membership, you can still review all listed milestones on the Illustrated List.
