Chicco Semi-Soft Trainer with Bite-Resistant Spout and Spill-Free Lid 7oz.| Removable, Non-Slip Handles | Top-Rack Dishwasher Safe | Easy to Hold Ergonomic Indents | Green| 6+ Months

I bought this because I had tried to use a straw cup with my infant but couldn't get her to understand how to use a straw, even with videos giving instructions; she just didn't understand so I bought these because I thought it would be easier for her, and it was! She figured out how to use this in less than a day and now loves it for water. This is a spill-proof cup if the inside silicone valve is in place, without it, it would just spill out everywhere. With the valve in, it does take a little pressure with suction to get the water to come out but not too much. I was able to teach her to use it by taking the valve out at first and she just practiced gauging how the spout worked. Once she understood it better, I put the valve back in and she eventually figured out how to use it. This brand is also nice because it is a one-size cup fits all lids so when we transition to the next cup, I can just purchase the lids instead and pop them right onto this one. Great buy. My little one is 8 months and I think this is a good cup to use to teach how to use a straw.

This is the best trainer I've used for a transition from milk bottle. The hard mouth piece makes it so they can't ruin the drop, but also it doesn't leak. 10/10 should have used this from the beginning.

Todo bien

Its a great cup! Took off one star for the plastic insert thing. I have 2 cups and both plastic things leak. I noticed a tiny slice/hole in both. Perhaps from after washing. Just be careful washing them. Other than that they're great.

Perfect first sippy cup for my grandson. It does not leak or spill on my floors or rugs and he figured it out very quickly.
