DS7 was a horrible sleeper until we laid down the law when I was pregnant with #2 when he was 3 1/2. We trained him to stay in his bed and call for his dad! Hahaha! He still does it! He was never much of a napper. He's very high energy and does not need a ton of sleep.
DD3 is climbing to our bed almost every night. She's driving me crazy right now. She was actually a fairly good sleeper as an infant though (compared to DS anyway). I think the stimulation of her older brother helped. She just gave up all naps fairly recently, although it has been on and off for at least 6 months. People regularly comment on how "high energy" they both are.
Anyway - misery loves company! Last night I ended up on the couch because when DD ends up in our bed she usually ends up pushing me out.
