I don't know what kind of cup to use for ds (21 months) when we're out and about even though he can use anything - open cup, sippy, bottle, sports top, straw, etc. The problem is, he is a bit destructive and bites and pokes anything soft. Also, I hate cleaning cups with lots of fiddly bits (think born free sippies). We have a foogo sippy which is OK but he is a bit old for imo. Can anyone recommend an indestructible, non-toxic, easy to clean straw or sports top water bottle?
