Actually not every cry is a need for milk. It can be loneliness/fear/insecurity, etc. Latching on solves everything at one shot.. whether filling the hunger or keeping her secure, since she’s close to you. You can try using a tight swaddle and holding her close to you, instead, and walk around a little. You can also try patting her firmly (cup your hand) to call her down. Don’t be depressed.. it gets better okay? My LO used to nurse on me for 2 hrs
