My son is 14 months and I’m currently 9 weeks pregnant. My doctors told me I need to wean by 20 weeks. Any advice? I work 4 days a week and on those days he nurses twice a day. But days that I’m home he nurses about 4 times ( morning, before naps, and once before dinner). He screams bloody murder when I try to not nurse him and has a tantrum, I feel bad but need to follow doctors orders. Any help would be great. Thanks.
