Sippy cups are over-engineered.

I hate sippy cups. They're expensive, over-engineered pieces of crap that only work 50% of the time.

When they do work, they break after a couple of weeks.

Unfortunately, right now Jake can only drink from sippy cups - so we have to buy them. We have about 20 of them.

We tried a new one yesterday and Jake wouldn't drink from it. I started getting mad at him. Then Cindy gave me the cup and said you try to drink from it; I tried and did not have enough sucking power in my lungs to get any liquid from it.

That's ridiculous.

Each sippy cup comes encased in a monstrous plastic shield that can only be removed by a chainsaw.

They come in a million different pieces, and you have to read instructions on how to put it together. Invariable, once you've assembled the cup, it leaks.

You can't wash it in the dishwasher or it will warp the sensitive plastic. The nipples are cheap pieces of crap that break when your child bites them.

Can you buy nipples separately? Yes - for the most part. But some sippy cups require that you buy a whole new cup every time the nipple breaks. (!)

Each piece of the sippy cup looks like it could fit in any other sippy cup. So, if you're using and washing 2 or 3 different sippy cups, you have a jumble of pieces that may or may not fit correctly together.

I've taken a picture so you can see this for yourself.
