My baby is no longer a baby

Over the last month or so, bedtime & especially naptime were becoming a battle. Naps became hit & miss & although we always tried, he usually refused to take one. Sometimes he'd throw a leg over his crib or pack n play, but we all kept telling him it'd be a bad owie to fall... in hopes it'd keep him in there. Well, it worked up until last week when he was at his grammy's & when she went to check on him she hears a knock on the door & sure enough he'd gotten out & was pretty pleased with himself. The next few days he'd threaten to do it in his crib, but we'd tell him it was bigger than the pack n play & he could get hurt. Again, that only lasted a short while. The other day my came to our house while I went to work & he gave her quite the fight going down, but she knows he will do that sometimes then go right to sleep. She can't stand hearing him cry so she went out & sat on the front porch. Not 10 minutes later she hears a knock on the front window & a little voice saying "hi gammy". Yep, he was even more pleased this time.
We knew the day was coming, but I just really dreaded the transition into a toddler bed. He's just such a busy body & doesn't do well going to bed anywhere, but the crib. Luckily, his crib turns right into a toddler bed so its pretty much the same thing without a side rail. The whole evening we practiced going to bed & tried our best to cheer him on so that bedtime would go smoothly. We cleaned out his room & took out all the toys & anything dangerous then put a door knob cover on the door. At bedtime he as excited so he let us tuck him in & go out without any problem. I think he thought it was still a game because when he realized he couldn't open the door he was pretty mad. After only ten minutes of rattling the door & fussing, all was quiet. When I went to check on him, I thought I'd find him on the floor, but to my suprise, he had completely tucked himself in & was sound asleep! He slept all night & in big boy undies too!! The last couple nights he's been more testy about going to bed, but does fine once we close the door. I just can't believe its gone so well. (knock on wood). This was the last "baby to toddler" transition so its official.... He's a big boy now! Still wondering where the last two years went...
