We never invested in a baby monitor when our daughter was born. Honestly, our apartment is so tiny we figured we'd hear her if she needed us, even with both bedroom doors closed. We always have heard her, loud and clear, when she's ready to wake up or talking to herself or sometimes even when she rolls over hard and whacks into the wall of the crib. But I do sort of wish we'd bothered getting a video monitor, because it's fun to get a peek at the things your baby is definitely doing while you're sleeping. Spoiler alert, it's not always sleeping, dear reader.
Half of what we know about how our daughter spends her time while we're sleeping is because we spent so much time traveling to visit family and sharing a room with her. We'd sneak into the room to go to bed long after we thought she was asleep, only to find her chatting away to her stuffed animals or just laying there staring at the ceiling. It certainly made me wonder about all those times I'd close the door to her room when putting her down for a nap, her eyes still open and her little arms still wiggling around. Sometimes when she'd go down for a nap she wouldn't make a peep until an hour or so later. Did she ever fall asleep in there, or was she just staring at the mobile?
The most important thing about what your baby is doing while you're asleep is that you're asleep, right? However, and just for kicks, here's a list of what your baby is probably up to in there while you're resting up for the next day.
