He's 6 months and one week old, but he was born a month early, so more like just over 5 months... Every now and then he'll make it past the 45 minute mark on his own while at the sitter's house, but never for me! He's had a cold for 10 days now, so that's throwing everything out of whack anyway. I just look forward to the day when he'll make it longer than 40-45 minutes on his own. This afternoon, he slept 45 minutes, woke up unhappy, and I had to calm him down (shush, let him cry some, pick him up, etc) for almost an hour, at which point he fell back asleep for an hour. I've read everything in the world, lurked on these boards, asked around... and I can't get him to be consistent. I guess he's just got my stubborn and strong personality and will outgrow it when he chooses!
