How do you measure a baby's length?

While your pediatric health care provider will certainly take measurements of your baby during office visits, many parents like to keep track of baby's measurements at home. The measurements that pediatric health care providers and parents are generally concerned with include length (or height, once your child can stand), weight, and the circumference of your baby's head. You can then use these measurements to plot your baby's growth on a growth chart.

Lay the baby on his back, gently straighten his leg and make a mark under his foot - make a mark where the top of his head rests. Move the baby. Using a tape measurer - measure the distance between the two marks.
