No one can fully prepare you for the crazy, sleepless, shower-deprived, always-a-poop-with-your-name-on-it life with a newborn. But Amber Crosby sure comes close.Her business, Baby Bump Planning, gives expecting families the push they need to get ready for a little one’s arrival. With a focus on compiling the perfect registry, she offers several personalized packages at prices that won’t break the piggy bank.Starting at $40, she’ll offer a custom list of everything you need to care for a newborn up to 2 years, including details like how many of each size diaper you should start with. For $190, she’ll also make a house call to give tips on everything from space saving in the nursery to car seat recommendations. Finally, for $390, she’ll do all that, plus accompany you on two hour-long visits to baby stores to demonstrate products and answer burning questions (umbrella versus jogger? sling or back carrier?).Of course, you can tack on other services, including shower invites, birth announcements, and scrapbooks.
