Oh, hon... {{{hugs}}} to you. I so seriously could've written your post 8 months ago. All the worries & trying to do what's best for your family. My DH thought I was a little obsessive about it
, too, but he tried to be as supportive as he could.
Well, I'm here to tell you it can be done.
DS will be a year in 2.5 weeks, and we're still at it. I started back to work when he was 4 months. I, too, have worried over dips in supply, spills at daycare, and low stocks in the freezer. But I've kept at it, one day at a time. A regular pumping schedule at work really helps, as does pumping when you can on weekends (after he's nursed). DS was 5.5 months when we started solids (a great place for DH to help!), but he mostly depended on milk for his nourishment. It was that way for a few more months. He still depends on it a lot, but solids have taken an increasing role as he nears a year. HTH. And more {{{hugs}}}.
