The Baby-and-Me Scale is designed to help mothers keep track of their own weight and their baby’s weight in a smart way. It can withstand a maximum weight of up to 330lbs (150kgs) and is powered by AAA batteries (LR03). Babies and very small children can be weighed while being held in the arms of a mother or helper. The Scale provides measurement reading, history and recommendations via "Hubble Connect for Smart Nursery" App. The app also calculates your BMI according to your weight & height.
