"I'm 'on' all day, carrying my girls around, changing diapers, racing to run errands only to race home for naptime. By the end of the day, I feel like I've been hit by a truck!" --Michele de Bourbon, New York City
How to deal: First, remind yourself that you're doing the best you can. "Caring for two is taxing, physically and emotionally. You're dragging car seats and carrying around these little bodies," says Sank. "But what's harder is that they aren't rational: They need you to do everything and they can't tell you what exactly they want."
Then, remember that if you try to do it all alone, you're headed for burnout. Hire a sitter or lean on friends, even for an hour. If that's impossible, carve out downtime during the day. "Carleigh was 17 months old when Luke was born," says Melissa Breen, of Manhasset, New York. "When I was at the end of my rope, I'd strap them in their car seats and go for a drive. They'd snooze and I could recharge." On the way back, hit the drive-thru for coffee; it can be a godsend when your patience is shot!
