13 month old co sleeper

Jazmin • 21 | Mama & wifey
So my baby girl still sleeps in bed with us, she basically has since she was born. She is now 13 months & I honestly can't remember the last time I actually slept through the whole night. I still breastfeed her throughout the night since doctor said I can if I want since it's breast milk (& since she's underweight it makes me feel a little better tbh). I'm sorry but I can't do it anymore! I'm exhausted! Is there any way to just stop breastfeeding her completely while she's still in bed with us?
