Glitch 1: Date night. Yes, you can drop the baby off at grandma's so you and your hubby can still enjoy date night, but don't plan to be out too long. You can only neglect the need to feed for so long. Date nights still happen, but they are considerably shorter.
Glitch 2: Dishes. Dishes get done, but usually not until the next morning. You eat dinner, you change baby into pj's and clean diaper, you feed baby, baby goes to sleep, you tuck in hubby, you're exhausted. Dishes are for mornings now.
Other than that, for the most part, it's business as usual, and I love, love love mommyhood!
