Not producing enough anymore


I’m getting discouraged, when I’m home on my days off with her I BF her whenever she wants. She isn’t happy for long before she wants more. She hasn’t been napping as well as she use to, and isn’t sleeping through the night like she use to, when I pump at work I only get 4 ounces. When we make a bottle of formula she downs 6oz like it’s nothing and is so content for hours. I’m getting discouraged because I’m not making enough to keep her happy. I’ve recently started feeding on both breasts when I was only doing one side before and it hasn’t made a difference.

Any words of encouragement ? Tips? Tricks? I don’t want to give up BF yet 😔
