Make sure that the carrying bar on the infant car is locked and the child is strapped in BEFORE you pick up the chair with the baby in it. Otherwise, the chair could suddenly shift vertically and the baby could fall out and right on the floor. Not that this happened, of course. This is hypothetical. This in no way happened to me at 2:14am on Thursday night. And I didn't feel terrible, either. Nope.
On a completely separate note, Lilah doesn't cry right away when she gets hurt. She looks at you with this "What the hell was that?" look, which morphs into a "Why would you do that to me?" right before she starts to wail. It's so sad and so cute all at the same time.
One more thing... be VERY careful when moving the baby during a nap. The disturbed wake-up is extremely ugly to witness and requires special attention by Mommy. This can cause the offending father a great amount of grief.
