Sometimes it helps to hear (or read) these things.
“Mamas, I want to tell you the truth. And here it is: You will not get anything done when you are home with a baby. And anyone who told you otherwise is not being very forthcoming (or perhaps they just have a lousy memory). You might get yourself fed. You might get yourself dressed (then again, you might not). You might take a walk (it makes baby happy). You might have a short phone conversation or start a load of laundry, neither of which you will finish. This is your new mom normal.
So what are you doing all day? Not much that can be measured, really. You’re simply responding appropriately and with patience (through fatigue), to smiles, to tears, to hunger cues, and to drowsiness, teaching your baby how to navigate this complex and (to a baby) highly emotional and raw world.”
