Let's be honest. Children, while cute, sweet, and adorable, are certainly not gentle when it comes to their belongings. Not gentle at all. So any time we go to make a purchase for our son we take a few things into account - ease of use, durability, easy to clean, safe, etc. The standard things. There are some products that meet expectations, some that fail expectations, and others that exceed expectations.
In this particular situation, Nuk has made a product that well exceeded our expectations - cups. Our favorites are the Gerber Graduates. We chose Curious George because our son loves him. But the cup itself is outstanding. It is easy for our son to hold, carry and drink from even while on the go. It is durable - it gets tossed and dropped fairly often and keeps on going. And it does not spill even after all of the abuse it endures. There is a special attachment inside the cup that prevents spilling. Even when the cup is turned upside down, it does not spill out and make a mess. It is fantastic. We can let our son walk around the house or sit in his car seat without fear of him taking a bath while drinking his water.
We highly recommend this cup from Nuk. It is a great value and great quality. If your child is anything like our, this will save you some clean up and headaches.
