I have been meaning to write a post on this for a few months now. I was just "reminded" of this after reading Adrienne's post at Our Unexpected Journey. Bennett (Adrienne's son) is 9 months old today and is learning to use a sippy cup. Although he is practicing with a sippy cup, Adrienne has ordered him a Honey Bear Cup so that he can transition from a bottle to a straw cup, and it has not come in yet. Here is short article from Parenting magazine that gives a brief summary of the benefit of a straw cup vs a sippy cup.
Anyway - Adrienne mentioned how she wished there were handles on the Honey Bear Cup (and I don't think I have found any straw cups that have handles) & I thought the same thing. I found something called Lilybugs on the website http://www.mom4life.com (I have found LOTS of great things on this website:) I thought it looked like something that might work... I ordered one (they have free shipping!) and Whitney LOVES her Lilybug! It really does help with learning to hold your own straw cup (although, Whitney has figured out that she much prefers to have us "hold" her cup for her, even though we KNOW she is capable of holding her own cup. She is working us!!!) Lilybugs have even won the 2006 iParenting Media Award in the categories of "Feeding" and "Hot New Product". The best price I have found is on the mom4life website (especially with the free shipping... it is a better deal than ordering direct from the lilybugs website). They have both "boy" and "girl" designs... Here is a picture of Whitney's "Lilybug" :
