Quitting the T

Me

So im over here 16w pregnant almost 17w and breast feeding has become pretty uncomfortable and a little too painful now. My whole left side is hardly expressing milk, just turned into mostly colostrum, my right side still lets milk out (not like a fountain anymore 😂) but id like to quit breast feeding my daughter now due to the pain and lack of sleep its caused..shes 19/20months so well past 6m but i also feel really guilty about it and have had 0 success when I do try weening her. Any advice or helpful tips? Do you think she'll stop if both breast go to colostrum? She does favor the right side more but ive been trying to keep her sticking to the left 😂
