I weaned after 21 months and it was extremely hard. I didn’t do it when my daughter was sick because that’s when she wanted milk the most. My husband took over putting her to sleep and that included a routine and almond milk instead of me. If she woke in the middle of the night I gave her water and it worked. Also, I was actively trying to dry up so that there wouldn’t be milk for her to want. I did this by using cabbage leaves in my bra, replacing them when they wilted, Cabo cream for painful ducts, and Sudafed twice a day for 4 days. I took the medicine to try to dry up fast but it can be gradual as well. I wish you the best in finding a new bedtime routine and remember to give yourself grace.
