The draw of NUK's Learner Spout Cup ($9) is the soft, silicone spout, which is designed to mimic the nipple of a bottle, easy the transition. — Lisa
How quickly did baby take to it? The ergonomic design of the cup seemed to work on my little guy — he reached for the handles and got the gist of how it worked right away.
Is it easy for tots to pull water out of it? It took my (at the time) 6 month old a little while to actually get fluid out of the cup, but once he got the hang of it, it seemed to come out at a good pace. We haven't gotten to this point yet, but one complaint that other users have is how easily the silicone spout stretches or tears.
How easy is it to clean? Once it's disassembled for cleaning, this cup has six parts, making it a bit of a hassle.
