My twin boys are 2.5 now. Also the result of tens of thousands of dollars of IF treatment. I, too, SKIPPED back to work. I don't miss the newborn stage one iota. Breast feeding newborns gave me such anxiety they had formula from the jump. Pretty healthy too. Jack had acid reflux ... so he cried a lot. So it was rough. My kiddos didn't STTN until 16 months.

What you are feeling is so so normal. I promise it gets better. If you have someone to help rely on them, even if just to run an errand or take a shower.
