If your first was a good sleeper, was your second a horrible sleeper? I've heard this is a common theme among a lot of my friends and family.

My son is 17 months and I'm not pregnant again yet but hoping to be soon -- and I have to say this is one thing I'm terrified of. My son STTN at 2 months old, sleeps 11 hours straight at night and takes a 2-3 hour nap a day. He loves his crib so much that in the morning he will lay in bed slowly waking up and then play/talk to himself for a good 45 minutes before we go get him. He's always been like this -- so I feel like there's no way we will be this lucky next time around!

So if you have two or more kids, were they completely different in their sleep habits?!
