Growth Chart Mysteries

Month 5, Week 3

At every visit, your pediatrician measures your baby's length, weight, and head circumference and records them on growth charts as points plotted on a curve. This compares your baby's growth to that of other boy or girl babies the same age.

You should know:

  • The percentile numbers on growth charts aren't like test scores. Your baby can't fail. They do not need to be above 99th percentile. It's just how they compare to other babies their age right now.
  • Healthy babies grow steadily. If your baby's weight drops down sharply, your pediatrician may want to watch them more closely.

Your Baby's Development This Week

Your baby's eyes are growing up. Their vision is still maturing, but it's already improved dramatically. Here's how:

  • Their eyes work together well enough to follow a moving object, such as a toy truck rolling across the room.
  • Their ability to see a wide range of colors has blossomed. They also like shapes and complex patterns.
  • Babies love looking at anything new. So take frequent walks or visit stores for a change of scenery.
  • Mirrors fascinate babies because the image in the glass constantly changes. And it's fun to watch your little one realize that they are the baby in the mirror.

Month 5, Week 3 Tips

  • Don't assume that your baby's size predicts their adult height or weight. Their growth chart percentiles are just about their current ranking.
  • Never leave your baby alone on a couch, bed, or changing table. They could roll or wriggle to the edge and fall. The crib is still the safest place for them to sleep.
  • Set your home water heater so the hot water is no more than 120 degrees F, to prevent burns. Never leave them alone during bath time, either.
  • To watch for adverse reactions (vomiting, diarrhea, rashes) when starting solid foods, wait 2 or 3 days before offering a new food.
  • Manage your stress: Take brief breaks to relax. A happier you is good for your baby. Let grandparents help!
  • If you have a partner, share the baby bonding time. That includes baths, diaper changes, bedtime, and playtime.
  • You have so much to do, but time flies. Make it a point to enjoy your baby today.
