☼.S.
We were only down to maybe 2 short sessions/day when our daughter was 21 months old. We also co-slept so I had a sippy cup of water to offer if she woke up during the night wanting to nurse. After a few offers of the sippy cup of water, she stopped waking up and asking. Then I just explained that since she was a big girl now, mommy's body wasn't making any more milk. At that age, she totally understood that so it was nice to use reasoning.
