1 month old still eats every 2-2.5 hours

Y’all I am DYING. My daughter was born 9/18. We had difficulties with breastfeeding but she is pretty much exclusively breastfed now. Sometimes I give her 2 oz of formula before bed in hopes she will sleep longer. We had ONE glorious night where she slept two four hour stretches last week, but otherwise she’s getting up every 2 or 2.5 hours like clockwork. She eats that often during the day too but that’s no big deal when I’m awake. But it’s getting brutal for the nighttime.

Any tricks to stretch out the feeds???
