When to stop??🤷🏻‍♀️

My son is 6 months so we’ve started solids. Since it’s the beginning of him getting use to solids and I still breastfeed him I wonder how do I know when its time to stop breastfeeding??? I really didn’t expect to be going this long and I’m blessed to be able to! But how do I know when it’s time? Also does your milk just start drying up?? Ahh idk I’m new to all this and have no idea😅
