My daughter loves this cup! When I first started her on a sippy cup it was a hard spout and she had a hard time drinking much out of it. I'm guessing that she just didn't like that the spout was hard, so she was only willing to drink 1 ounce out of it at a time. Because of it, I didn't wean her off the breast until she was about fourteen months old and she was eating plenty of solids. A friend let her use one of their sippy cups and it was this one and Jenna didn't want to put it down or give it back. She LOVED the soft silicone spout and was totally chugging it down. She's willing to drink a good amount of her milk out of this sippy cup at a time and it's great! The only reason why I'm giving this an 8 instead of 10 out of 10 starts is because Jenna likes to bite on the sippy cup and I think that it'll break down easily and get holes in it while she's teething, which means I'll have to buy a new cup.
