12 weeks pregnant still nursing 14 month old!!

Victoria

Has anyone gone on a mini vacation (3-4 days) to stop nursing cold turkey rather than slowly weaning ? My 14 month old wants to nurse all day long and night and pulls down my shirt. I’m nervous if we wait too long he will get jealous of the new baby. I’m thinking the best way to stop completely is to leave him with my mom for a few days but can’t seem to find any relatable success stories. Any advice would be greatly appreciated!!
