fish tank and the sippy

so ben has had a fish tank for a few weeks now. he always had to see the fish when we went to the store, so one night jason brought everything home and set it up. (remember, he was the fish guy at sailfin in champaign...) lauren really loves watching the fish. speaking of the little lady, she never took a bottle, but did eventually take a sippy cup without the sippy part. basically it was poured in. because of that aspect she's never been able to drink on her own. yesterday i bought a different sippy...so now she's working on her independence. i can't decide if i'm encouraging her to revert back to infant suckingj rather than actually drinking...
