Cold turkey / gradul
There is no edict from on high that says kids have to be off breast @ 1yr. If your choice & kid willingly accepts chg then fine.
Some kids/moms can cold turkey with help of binding/pain control over a wk or so. Some drop/substitute a feed every day or two till their engorgement deminishes then they have less intense pain & spread it over the 2 wks it takes to come off. Good luck.
