Is it too late to breastfeed or pump?


My baby is 2 months and 2 weeks old, I was pumping for the first 1.5 months then for so many reasons I stopped and he has been having formula ever since.

Now I feel guilty, also I actually feel like the need to give him my milk. Is it too late? I feel like I dried out since I haven’t pumped in almost a month and my boobs almost went back to their old size.

This is going to sound stupid but... Is there a way to bring the milk back?
