2 Pack Sippy Cups with Soft Spout - 10 Oz Toddler Cups Spill Proof with Easy Grip - BPA Free & Dishwasher Safe (Blue & Green)

This is the best brand of sippy cup out of all that we have tried. I noticed my daughter would drink much less water with certain other brands (munchkin - all variations, tervis) and when testing the cups out myself, even I struggled to get any liquid. It seems most other sippy cups require a very powerful suck, and maybe this is fine for infants who are used to more vigorous sucking because they use pacifiers? That’s just my theory. Over time, the nipples of the nuby do eventually leak, but this is probably because my daughter sometimes bites them and tries to stick her little pointer finger in every crevice of the valve and nipple. The nipples can be replaced relatively cheaply though, so this is not a problem. If your child is not accustomed to a pacifier, I think you may like this brand of cup as well.

Easy to hold and doesn't leak

good product

I tried this to see how it worked and thought there was no way he’d get the water out but he did. Works well enough just not his favorite cup

Wash well easy to clean no spills

I wanted to love these. I really did. But I've run into a few issues that made these a disappointment.First, and most importantly, my poor kiddo ends up creating such a vacuum on these that the top and spout collapse and nearly invert. So between sips I have to open it just enough to break the seal, and then he tries again. It's usable - it's not like he can't get anything out of it - but it's uncomfortable and awkward for him, and it feels like a design issue.Secondly, the plastic is so smooth that any grease makes it nearly impossible to hang onto. Some bottles and cups have that slightly rough surface that can handle it, but these just become super slippery. And as my child is using these at mealtimes, his hands are often messy.Finally, all the swooping curves that makes these cups so attractive also make them super hard to mark accurately for fluid ounces. We're transitioning off of a bottle, and it's just an extra hassle to have to measure the water into another vessel before adding it to the cups when giving him formula. These were recommended to us as a good choice for transitioning from bottle to cup, but they haven't worked out well for us on that front. When he's older they will probably be fine (aside from issue #1 above), but if you're on the hunt for something for the in-between stage, I can't recommend them.

Era lo que buscaba, al principio a la niña no le gustaba, pero ya se acostumbró, hay uno que me derrama un poco, el otro no.

Good quality, no leaks, perfect for little hands.
