Withings Body+ Installation And Operating Instructions Manual page 39

For best results, we recommend you to weigh yourself when your baby is calm.
Note: you can use Baby mode for several members of your family. For example,
you may wish to add a profile for your baby to your account or create a separate
account for your baby. Please note that you can add up to 8 users to your
Withings account.
