hi based on my experience, you just cant let go of that
tell slowly, maybe you can use the ‘whining with love’ method
tell your child he should stop breastfeeding, try to start reducing the duration of breastfeeding
example: today breastfeeding 4x in a day,
tomorrow 3x the next day 2x
and if your child starts to whine, distract him and give him plenty of healthy snacks so he doesn't get hungry easily
Good luck!
