I know some here like SIGG bottles, Kleen Kanteen, FUNTainer, and such.
Anyway, I am tired of our standard sippy cups leaking in the lunchbox and want an alternative. Regular thermos or leak-proof plastic sippy cups are ok too. The cups will be used for milk 75% of the time. Is there anything bad about milk in an aluminum or stainless steel container? Seems odd to me for no particular reason. The cups don't have to retain cold, since I always pack an ice pack in lunchboxes. It just has to not leak and be appropriate for kids age 3 year and up (i.e. no soft spouts and good sized).
i found this informal comparison and testing, I stumbled on a site (http://zrecs.blogspot.com/2007/05/si...ree-sippy.html). Just wanted more info. and alternatives.
