Falling motivation

LO turns 5 months this week, and my motivation to EP is really flagging. She is going through a growth spurt that just won't quit and I'm having to dip into my meager freezer stash for the first time in two months. I will absolutely get her to six months but I'm realizing I don't want to do longer. But formula is so expensive! And I love how healthy she is! I dream about having more time in my day, to exercise or sleep, and to be able to lose weight again. I've gained so much back trying to boost my supply that I don't recognize myself. Ugh.
