I introduced the sippy cup to DS when he started eating solids. He would suck on it, water would come out, but then dribble out of his mouth. He didn't understand he needed to drink it. I've tried a few times and he doesn't seem interested in the sippy cup/water. Last night while eating out with some friends, I fed him some water through my straw (put my finger over one end of the straw and release the air once the straw was in DS's mouth). He drank the water just fine!

Do you think it's a sippy cup thing and that's why he doesn't drink it? Should I try another sippy cup? How much water does your LO drink when they were 6/7 months? Is it okay he doesn't drink water after a meal? He still gets his milk in between solid meals.
