4m wants to BF

Kimberly • Mommy to a little princess ❤️

So this is weird but my 4 m old NEVER & I mean NEVER wanted my boobs but I still kept massaging them so my milk supply wouldn’t dry. Now at 4m she’s got interested in them and started latching but I’m thinking she’s not getting anything out is there anything I can do to make sure she gets at least some milk. I tried pumping but I’m not even getting a 1/2 oz. is it too late for me is my milk supply completely dried out?
