Query: This cup is too hard to suck through.

My 13-month old has been drinking from a straw cup since he was about 9 months old. I read a lot of good things about this cup and ordered 2 of them. He didn't seem to like it that much and when I tried to drink through it, I found out why. You have to suck SO hard to get any liquid--I had a hard time with it so I can't imagine what kind of a time he was having! Leakproof is great but not if it means it's suckproof too. His favorite straw cup so far has been the Pigeon MagMag cup. The Playtex straw cup is also not bad but I would not recommend this Cupsicle straw cup to anyone.
