Keeping an eye on your baby's physical development is one of the most exciting and reassuring parts of early parenthood. However, minor measuring errors can lead to misleading drops or spikes on a growth curve. Here is a practical guide on how to record precise measurements at home.
1. Measuring Weight
For infants under two years old, accurate weight measurement requires a dedicated baby scale or a reliable method on a standard adult scale:
- Using a Baby Scale: Place the scale on a hard, flat surface. Ensure your baby is naked or wearing only a clean, dry diaper. Wait for the scale to stabilize before noting down the weight in kilograms.
- The Subtracting Method: If you don't have a baby scale, weigh yourself first on a digital scale. Then, step back on the scale holding your baby in the exact same clothing. Subtract your weight from the total to find your baby's weight.
2. Measuring Height (Length)
Before age two, children should be measured lying down (recumbent length). After age two, they should be measured standing up (stature/height).
Recumbent Length (Under 2 years):
- Lay your baby flat on their back on a firm surface, like a changing table or a blanket on the floor.
- Have a partner gently hold the baby's head straight, aligning it with the top of your measuring surface.
- Fully extend the baby's legs by gently pressing down on their knees so their feet are flat against a vertical boundary or ruler.
- Measure from the crown of the head to the soles of the feet. Do not measure along the curve of the body.
3. Establishing a Schedule
You do not need to measure your baby every day. In fact, daily measurements will show fluctuations due to hydration and feeding, which can cause unnecessary anxiety. The recommended frequency is:
- 0 to 3 months: Every 2 weeks
- 3 to 12 months: Once a month
- 1 to 2 years: Every 2-3 months
- Over 2 years: Every 6 months
