A lot of the pictures we've seen so far make reference to the fact that children dominate your life. This one goes a step further, and it's more accurate than you might assume it to be if you don't have a child of your own. Because you're on care-giving duty 24/7, days have a habit of merging together. The days become weeks. The weeks can, if you're not careful, turn into months.
When did you last have a shower? When did you last cook a meal for yourself? When did you last even leave the house? It's probably longer ago than you think. You're not consciously neglecting yourself; this is just what happens when you're so focused on your new arrival. Start setting reminders on your phone so you don't forget to do basic things. You'll be glad of the help when the alarm goes off!
