Don't panic, btw. He *will* eventually sleep through the night. Some children do it sooner, others later.
Well, now, let's difne "night" here. If by "night" you nean the time period in which you used to get blissful sleep, kiss it goodbye. Sure it's not every two hours, but then they get up at other times during the night. Let's not forget the inevitable "daddy, I'm sick" nights in which kid vomit makes its way onto - well - all over you.
No, I wouldn't expect a regualr great night's sleep for about another 20 years. You can get an odd good night on the occasions when your family takes him for you. Of course, then you wake up at 4:30 saying, "I miss little Dejan waking me up now." So I guess you really are completely hosed for the next 20 years.
So far I must say that it's been worth it.
Congrats again and enjoy!
