LO hasn't really cared much for water since we started at 6m but I wasn't too concerned because he was still nursing regularly. Sure enough, when we dropped to 3x a day he is drinking up a storm. He has really taken to the new straw cup and lid I just got and it's so nice because it just fits in the diaper bag and attaches on to most any glass.

Just wanted to share since lots of folks are always asking about straws!

It isn't spill proof if you turn it upside down, but is tip proof if it just gets knocked over. I like it because we can use it too for smoothies
