Is This Normal During My Kid’s Sleep? What Parents Should Know
It was 2:14 a.m. when I heard the thud. I was already up, waddling to the bathroom for the third time that night, my second pregnancy turning my bladder into an overfilled water balloon. The thud came from my 7-year-old Mia’s room, followed by a soft bumping sound that made my heart jump. I grabbed my phone to use as a flashlight, socks slipping on the hardwood, and poked my head around her door.
The moon was coming through her blinds, streaking the walls with blue. Mia was standing in the middle of the floor, one foot tangled in the rug, eyes wide open. She stared straight at the bin of stuffed animals in the corner, not moving. I whispered her name: “Mia? You okay?” She didn’t answer. She just blinked once, then turned slowly toward the door, misjudged the frame, and bumped her shoulder on the trim. I stepped forward to catch her, and she mumbled something that sounded like “more blue paint” before leaning into my side. I’d read about sleepwalking before, but nothing prepared me for how eerie it is: she’s right there, but she’s not really awake.
I tried to shake her awake, like every half-read 3 a.m. internet article forgot to tell me not to. She just pulled away, frowning, and started crying a little, confused. I calmed down, guided her back to bed, pulled the covers up, and she was asleep again in two minutes. I sat on the edge of her bed for 20 minutes after that, scrolling WebMD, my mind jumping to every worst case scenario: seizures, anxiety, something wrong I’d missed.
I called our pediatrician that morning, got an appointment for later that week. While I waited, I texted our first grade parent group chat, and half of them replied with their own stories. Sarah’s 5-year-old grinds his teeth so loud at night she can hear him through the baby monitor when she’s in the living room. She was convinced he’d need braces by second grade and that the grinding was from stress about starting school. Mike’s 6-year-old talks in his sleep almost every night, once yelled “STOP STEALING MY GOLDFISH” so loud the dog jumped off the bed. Mike was sure he was having nightmares from the 10 minutes of Bluey he watches before bed. Jen’s 4-year-old sleeps with her eyes half open, which Jen thought meant she was never actually getting rest.
When I sat down with our doctor, she nodded before I even finished talking. She said around 7 out of 10 kids will have at least one unusual sleep behavior between ages 3 and 12, and most of it’s completely normal. It’s not anxiety, not a sign of a hidden problem, just a kid’s brain sorting out all the new stuff it’s learning every day. The part of the brain that controls waking and sleeping is still maturing, so sometimes the lines blur a little.
She gave me a couple simple rules I’ve stuck with, and I passed them along to the other parents. For sleepwalking: don’t wake them up, just gently steer them back to bed. Wake up a sleepwalker and they get confused, sometimes scared, and it takes them way longer to go back to sleep. If you’re worried they’ll hurt themselves, just block off stairs and lock exterior doors before bed, that’s easy enough. If it happens less than once a week, and your kid is fine during the day—no constant tiredness, no random mood swings—you don’t need to do anything else. For me, cutting out Mia’s after-dinner apple juice cut down how often it happens, because a full bladder can trigger sleepwalking, that was a small change that made a big difference.
For teeth grinding, she said most kids grow out of it by the time their adult teeth come in all the way. It’s usually just their jaw adjusting to new teeth growing in, not stress. The only time you need to check in with a dentist is if your kid complains about jaw pain when they wake up, or you can see visible wear on their front teeth. Sarah took her son to the dentist after that, and he said everything was fine, no need for a mouth guard or any treatment. For sleep talking, same thing: it’s just the brain firing off while it processes the day’s events, not a sign of hidden stress or repeated nightmares. Most kids don’t even remember it, so don’t press them about it the next day, that just makes them confused.
The only red flag she pointed out is if the behavior happens every night for more than a month, if your kid regularly hurts themselves during an episode, or if they’re always tired or irritable during the day, even after a full 10 or 11 hours of sleep. That’s when you should check in with a doctor, just to rule out anything else.
It’s been six months since that first time Mia sleepwalked. She’s done it three more times, once she made it all the way to the pantry and ate a granola bar standing up, and didn’t believe me when I showed her the crumpled wrapper on the counter the next morning. I still keep my phone charged by my bed, and I still pause for a second when I hear a weird noise down the hall at night. I haven’t had to go back to the doctor yet, and most nights I just roll over and go back to sleep after I check on her. Parenting is full of these little moments, where you’re standing in the dark asking yourself “is this normal?” Most of the time, the answer is yes. It’s not a problem to fix, just another weird, messy part of kids growing up. Right now, that’s enough for me.
