Admittedly, I didn't really start reaching for them until my daughter was about 2.5, when her appetite called for larger plates. Until then we were just using the 6 inch ceramic plates that came with our set. However, my daughter has never tossed a single plate, even at an early age, so if that had been a problem I definitely would've reached for these sooner.
They are extremely durable, and I love the fact that the silicone can go in the microwave, so there is no need to microwave children's food on plastic. After heavier use recently, I have not noticed any wear, even to the etched design. While I love the fact that both the glass and the silicone can go in the dishwasher, it is worth mentioning that I separate them to do so, and water inevitably gets trapped under the silicone rim. I end up drying it when I take it out, and storing the dish and silicone separately so no remaining water gets trapped in there. Not a very big deal, but worth mentioning.
Overall I think Brinware plates are a fantastic option for those seeking plastic free dishes for children. They are even large enough (7.5 inches) to continue to use with older children, with or without the silicone sleeve - a very worthy investment. They also have matching placemats with cute alphabet designs on them.
