Why do we congratulate people so enthusiastically when news of a new baby comes out? It's A LOT of work, among other things!!
I remember reading a specific reference that a Russian woman made to this, noting that in Russia, news of a new arrival is met with a more realistic attitude--"Oh, that's good news, but there's a lot of work ahead for you." Whereas in America, how do we respond? "Yayyyyyyyyy!!!!! Congratulations!!!!!!" You'd think that having a baby was synonymous with having scads of money flung at you for you apparent reason: everyone is excited about it and kinda wants in on the action for the good parts but no one wants to really help out with the bad parts (like paying taxes on your lottery winnings).
I'm not about to pretend that I don't also share this energetic, over the moon, as-if-it-were-happening-to-me response. I can't help it. You get all hopped up on happy thoughts of warm snuggly, toothless little coo-ers who smack their lips and have those ever-so-adorable yawns and good morning stretches.
And, for that matter, why do we get so excited to share such good news? Do we revel in the adoration? Secretly desire the lavish attention showered on us when it's our turn? Ignore the rational knowledge that reminds us, Warning: massive amounts of work ahead with little free time for yourself for at least a couple of years!!!
Whatever the case may be, happy news and cuteness is always appreciated.
