If you own Withings (Soon to be Nokia) Body and Body Cardio you can now use Baby Mode to track your child’s growth. Baby Mode allows parents to follow the growth of their child with Body and Body Cardio by weighing themselves with the baby in their arms.
It is highly precise and takes accurate measurements up to 0.2 lb / 0.1 kg. This is how it works or can be put to use.
1. Create a profile for the baby in the Health Mate app (specify gender, height & most recent weight).
2. Step on the scale alone & go through the complete weigh-in process.
3. Within 5 minutes, step on the scale again – with the baby this time. The parent’s weight is automatically zeroed out, and the scale will recognize the baby’s profile to display the baby’s weight
4. Measurements will be sent automatically via Wi-Fi or Bluetooth® to the Health Mate app, where the parent can follow the baby’s weight trend and view ranges showing what is healthy for reference.
