I don't know what the weather is like where you are, but we're about ready to burst into flames here! I'm originally from the northeast, but I'm getting to experience weather variety thanks to being a military spouse. So, instead of playing outside every afternoon, we have been taking shelter in the air conditioning until AFTER dinner. So here are some random thoughts I thought I would share.
First of all, sippy cups... I hate them. We tried to skip them completely. It was going well until we visited the grandparents for several weeks and sippy cups were just easier. We had opted for the kid cups that look like travel coffee cups. I just removed the valve and its a great training cup! I also found, but haven't tried yet, a great product, the "Oxo Training Cup." It's similar to what I have rigged up with the cups we have, so I don't think I will buy any more cups.
