It's been almost a week, so I feel like I can say this safely. Mrs. B has weaned Oliver.
She cut off "nummies" (our little word for nursing) except for nighttime feedings a month or two ago. Last week, as we were driving home from something-or-another, she told him that the nummies were all gone.
He started negotiating with her - "almost gone?"
"No, honey," she said, "all gone."
"Almost gone," he insisted.
"No, baby, all gone." We both started worrying, and I found myself a little teary. He really seemed upset at this sudden development.
And then, that night, he was fine. He asked once for his nummies, and Mrs. B told him they were all gone, and he just turned over and went to sleep.
The next night, he got a little upset in the middle of the night when he couldn't nurse. But it's gone surprisingly smoothly. She's thinking we could have done this a long time ago, but maybe we just waited until the right time.
