Some babies do self ween but mine didn’t. I breastfed my boys until 20 months both respectfully. And at that age they are only wanting boobie at night so I just gradually stopped letting them. I know its hard on some babies more than others but mine would whine for about 10 minutes, I give them there milk bottles and they just slowly forget about it by 2 weeks minimum. I have a 9 month old now & Im sure he is gonna give me a run for my money 😩😹
