Bring back milk supply?

Me

How would I go about bringing back my milk supply ? I stopped breastfeeding about 2 months ago and I would like to bring back my supply for the night feedings my son has sometimes. Making a bottle at 3am is just so cumbersome.

When I squeeze my nipple there’s a little bit of milk that comes out but my supply has dried up for the most part as my boobs are super soft and saggy.... is this even possible?
