Children's bedtime

How many of you out there have problems with your children at bedtime?  My son who is 2 1/2 goes down great for nap.  Even though I lay with him, he is out in 5 minutes.  Bedtimes however is another story.  I have tried skipping nap and tat works until he falls asleep at 5 pm and wakes up at 7pm.  I lay down with him and 20-30 minutes later we are still there.  I put him in his bed repeatedly and still he fights it.  I know that it is my fault we are at this juncture, however, I just needed to vent my frustrations into the void.  So as Meg Ryan says on You've Got Mail, "Good night dear void".
