hi gals,
not much success with the straw cups here, but then i must admit i haven't been trying that hard, because...
DS will drink out of a water bottle with the sports nipple!
we found this purely by chance -- he likes to try and drink from anything that i drink from, a cup, a glass, or even a gatorade bottle! one day i could only find non-refrig water at the store in the sports bottles, so bought one of those. i took the nipple off first, but though i'd try him with it on. well, that boy just latched on and started sucking away like nobody's business. i almost fell off the wall we were sitting on.
of course, regulating the amount of water he keeps in his mouth before he swallows is a different thing -- ds doesn't seem to get that at some point you do have to swallow, and pref. sooner rather than later to avoid spluttering or dribbling.
so we bought a lot of 8oz water bottles with sports nipples from the store, only to get home and find out that they were "kidproof" -- i.e. nonrefillable! i'm not quite sure how the cleaning and sterilizing would have gone anyway, but i'd have been willing to give it a shot.
anyway, just thought i'd pass this along.
