Now that DD2 is a month old, the drudgery of newborn care has become REAL. Anyone else feel this way?

Oh sure I still have those magic moments when I stare at her while she's sleeping, or feel her warm head underneath my chin when I'm holding her over my shoulder, but I am more than tired...I'm worn out by the tedium of baby care. As a STM none of this should be a surprise, but yet it is.
