Today I had to leave the room during lunch for a moment. When I got back, M2 had M.G.'s glass of milk and was tentatively taking a sip. He's finished off the milk in his cereal bowl a few times, but turns his nose up if you offer it to him in a cup.
M.G. has been pressuring him to try it because he is almost 2 and that is when she started drinking milk. So today she slid her glass over and was encouraging him all the way. He drank a few big sips before accidentally spilling it all over the kitchen and he had the biggest grin because she was egging him on.
She has great power here, we'll see if she continues to use it for good!
