Sippy Cups

We've tried getting Gavin to use many different sippy cups the last couple months. We've bought so many different cups, but he couldn't figure out that he had to suck on it for the water to come out. We even tried using a straw. The only way he would drink anything was out of a cup or water bottle. Then today my friend Jami was watching him and she realized whenever she watches him he never drinks anything(except an occasional sip out of his water bottle). So when they were grocery shopping she bought him a Gerber Nuk Learner Cup and it worked. It has a softer nipple, maybe that's why. At least now I can rest assured that when Gavin is away from me he is getting something to drink.
