Hi, I've been looking for a straw sippy cup that dosen't leak. I've tried the munchkin ones and they claim is spill proof but it leaks every time. I'm skeptical of others that say it's leak proof/spill proof. Which ones have you used and did not have issues? Thanks!!

Re: Straw Sippy Cup that dosen't leak?
My Tommy Tippee never leak but she really has a hard time getting anything out of them. Almost like sucking through a straw with a hole. I tend to think it's user error but can't figure out what that error is.
With munchkin we seem to have a problems with it coming out of the straw, which can sometimes be fixed by losening the lid a bit.
The only cups we have not had any leaks or issues with are the hard spout cups with rubber stoppers.
We have three of these. They leak. They're also masters at shooting warm milk out on their own.
I have used the Playtex Insulator Twist & Click sippy cups for a few years (both regular and straw) and have never had an issue with leaking. I've tried others and these are the only ones that never leaked. These are the only ones I will use now.

Here are my two favorites:

I use those Playtex insulated ones the pp posted.
I have never had a leak with them and I put all sorts of stuff in them.
The trick is to make sure the little square tab on the bottom part of the straw lines up with the middle part of the straw where the stopper is attached.
Ive tried doing this and they still leaked. Idk why even half full or loosening the lid the fluid would still come up the straw. Im going to try the tommy tippee cups.
Hmmm...that's so interesting to me. I haven't had one leak yet and it's been over 3 months.
I do pull the straw through until it pops and then squeeze the tip a bit. It seems to get the extra air out.
We have 3 of these and they all leak.

I'm not sure there's a cup out there that won't leak when LO plays his favorite cup game... turn it upside down and beat vigorously on ground.
However, we're very happy with the Nuby straw cup, and I haven't had any experience with it leaking in regular use and play.
