You finally breakdown and confide in your friend/husband/auntie/neighbour that you're EXHAUSTED (if they couldn't already tell by the bags under your eyes) and they respond with the classic "sleep when the baby sleeps!" Unfortunately, mum's aren't often only changing nappies and burping babies. They also cook, clean, go to work, and everything in-between.
And even if you do have the time, mum's will know that you seldom get a moment to yourself. So when the baby does eventually fall asleep, I like to grab that moment and scroll through Instagram or Facebook, to remind myself that I'm not just a poop wiping, baby feeding, booger wiping machine.
