Our girls certainly have some similarities, but there are very clear differences that are starting to show as Caroline grows older. For example, Lucy is very clearly more cautious than Caroline. (Side note: this is a direct result of Lucy inheriting my tendency to think too much.) Lucy has to warm up to an idea before she can act, whereas Caroline will jump in headfirst and ask questions later.
The first time we went to a water park Lucy was 3 and Caroline was 15 months old. Lucy would go in the kiddie pool, but we had to coax her to do anything else. Steve offered to go with her on other slides, I went down a big slide to show her that it was fine, we watched other people go ... it didn't matter. Finally by Day 2, Lucy ventured out of the kiddie pool and eventually loved it.
Contrast this with Caroline: she grew tired of the kiddie pool after a half an hour (after she was scolded by a lifeguard for going headfirst down the slide) and immediately wanted to go down the big kid slides. We cautiously went with her down a big slide assuming that one ride would freak her out. Wrong. She loved it and boycotted the kiddie pool for the rest of our stay.
Take this same adventurous spirit (or lack there of) and apply it to sleeping arrangements. As a toddler, Lucy had no idea that she was physically capable of getting out of her crib. I am sure that even if she had an inclination to get out of her crib she was scared off by the fall to the ground. She was 3 years old when we finally transitioned her into a toddler bed, and the only reason that we made the switch was because we were getting tired of lifting 40 pounds of preschooler into a crib.
Now fast forward to nap time yesterday afternoon. We are visiting Cookie and Grumps, and so I took the opportunity to leave during nap time to go on a Target trip all by myself (it's amazing what you come to appreciate after you have kids). I laid a very snoozy Caroline into her pack and play and left assuming that she would still be asleep when I returned. I came back an hour or so later to find Cookie in the driveway with Caroline. Cookie informed me that Caroline hadn't slept and that she had climbed out of her pack and play several times.
We all figured that she was just a little too big for the pack and play, and so we brought the crib out of the basement. Last night Caroline was wiped after having a very busy day and no nap. I laid her down into her crib and she immediately went to sleep. Crisis averted, right? Wrong. This morning around 6:30 am I heard some movement in her room over the monitor. I then heard silence and figured that she had gone back to sleep. I then heard a huge BOOM and crying that followed. Yep, she was out of her crib and not very happy about it.
So, I guess we are officially out of the crib phase. Steve and I are not happy about it, but Caroline appears to be very proud of herself.
