How do your LOs do with them? We have tried multiple kinds including straw cups without much success. He just bites on the spout or straw. The only one I am able to use with him is a Tommy Tippy one, when it is tipped back the water comes out and he doesn't have to suck on it but I have to tip it back for him, he won't tip it back on his own.
I thought by now he would be better about taking the sippy, but maybe I just need to give it more time.

Lucas started at 6.5 months so the age range they use isn't very accurate.
so far we've tried nuk & tommy tippee, and avent regular sippy cup with soft spout which she mainly chews on. i bought the playtex straws and i'm going to try those. i also bought the sassy grow up cup which is supposed to be more like a real cup but w/o spilling.
she still barely drinks an oz of water a day so i have to start teaching her.
We have tried a few different kinds of sippys and the only one that DS was able to get the hang of is the plain cheap-o take and toss ones. They are not completely spill-proof but are really easy to clean and you get 5 of them for like $3.
He is just starting to get the hang of drinking out of a straw from a regular cup (with us holding it of course).
We bought the straw cup PP mentioned where you can squeeze the cup to help them learn.
Unfortunately I think she's learned that the straw goes in her mouth and them mama squeezes the water.
