C.O.
When I weaned I did it slowly. Like if it took 1/2 hour for them to nurse then I cut it down to 20 minutes and gave them regular milk. My kids were both over a year when I weaned so we never did formula, we went to whole milk. Then after a week I went to 10 minutes and then eliminated that nursing session. I only did one session at a time and I was still pumping at my regular time too. I eliminated the pumping last and the same way. I think doing gradually was easier and more pain free. Oh you will feel pretty full if you do it too quickly.
