All things matter — big or small. Your Child now starts to understand the concept of relative sizes.
How Your Child sees the world become more and more precise as they develop. By 6 – 9 months, Your Child may begin to understand relative sizes, such as how their parents are big and handheld rattle toys are small. The little one will also be able to use this concept as a clue to tell whether things are close or far away to them.
How to support this development
If you bottle-feed Your Child, get bottles in a variety of sizes and shapes so the little one will learn to distinguish relative sizes very quickly.
In addition, you can provide your child with safe toys of all shapes and sizes to play with. When you play with Your Child, explain what’s big and what’s small. Also, move toys close and far away from the little one so Your Child can develop their vision as well.
Note: All children develop differently and at their own pace. For children born preterm, the referred timeframe for achieving the various developmental milestones might be incorrect.
Sources: The information and graphs about when children reach specific milestones are taken from various sources, including the United States Center for Disease Control (CDC), the Denver Developmental Screening Test, and the State Institute of Early Childhood Research, Germany (IFP).
