These scales do the job but I thought buying specialised scales for weighing babies they would be better at doing it. In particular although they have three decimal places on the display, the last one is always zero. In other words they only weigh to the nearest 10 grams. So I don't see the point of having that last digit, and if you're going to use the scales to work out how much the baby has eaten by weighing before and after a feed then 10 grams is actually quite a large margin of error.
Also, although obviously it's always going to be a challenge to accurately weigh a wiggling baby, the scales seem to pick their moment to "lock" the weight somewhat randomly and it's hard to be confident that the measurement is accurate.
