I will never stress naps enough, but, hm. Honestly, pregnancy's weird. Everyone's different. If you want practical advice? Stock up on things you know you'll burn through quick early on. Diapers, wipes, creams. I had a monthly budget I spent on all that while I was expecting.
Don't fight your cravings. Give in, don't let anyone judge you.
Beware of grocery lines and crowded elevators when you start showing. Your stomach becomes a magnet for hands.
