This is a new phase I am NOT enjoying! Thomas has always been very good with drinking water from sippy cups, but recently he takes the water into his mouth then lets it all fall out, soaking his clothes. I'm not sure if he's just taking in too much water, or he's being silly and playing with it. I've had to start offering him water in a babies bottle again, he doesn't spit it out of that! Grrrr, anyone elses bubba done this? When do they grow out of it?
