The realization hit me when the bottle that she was using sprung a leak. Meaning: She bit through the top of it. When I was at the grocery store earlier, I went to get her another bottle. (Which looks eerily similar to the one up there. lol) When I picked up the bottle amongst all the other interesting sippy cups, I wondered, "What am I doing wrong?" After all, if I can't do something as simple as getting her off her bottle, I must be doing something wrong.
