I was at physical therapy this morning, wearing The Boy in the front carrier. He enjoys that - the motion of the exercises is pleasant to him, and he likes looking at the world from higher than the stroller allows. I was drinking out of my water bottle, and he decided that he wanted to play with it. So, on a whim, I decided to let him play with the open water bottle (with me holding on to the bottle, so as not to wear the water). He brought the open end to his mouth, I tilted the bottle up a bit, and he drank.
The cool thing about it? He did it a few times, and none of the water got on his clothes. And, I definitely heard him swallow. Pretty neat, no?
