I haven't used it as a toddler scale yet, but I use as the infant scale since I have a 3.5 month old daughter. We love not having to wait for our Dr visits to see how much she's grown! I also have fun weighing her heavy diapers too lol... super accurate and I put down a receiving blanket then zero out the scale so she has a nice soft surface that I lay her on to weigh her. I'm sure it would be fine without but I like to have the added comfort so she enjoys getting weighed.
I bought this scale because of the high weight capacity as I am dieting and have a large amount of weight to lose. The scale is so narrow that is is difficult to get your feet completely on the scale and to be balanced enough to get an accurate reading. The scale is very touchy about the readings and the plastic sounds like it's about to break every time you step on it. Not worth it in my opinion.
