Peace of Mind in a Tiny Sock

The media could not be loaded. This eufy Security Baby Monitor Smart Sock ended up being one of those baby items that made me feel calmer and more confident as a parent, especially during those moments when you just want to peek in and make sure everything is okay. From the very first time we used it, it felt reassuring knowing I could keep an eye on my baby’s sleep, naps, and heart rate without constantly sneaking into the room and accidentally waking them up. The sock itself is soft and gentle, and it fits comfortably without feeling too tight or bothering my baby while they sleep. I really liked how easy it was to put on and take off, even when my baby was wiggly or half asleep. Once it’s on, it connects through 2.4 GHz Wi-Fi and sends updates straight to your phone, which feels almost like having an extra set of eyes watching over your baby while you rest or get things done. One of my favorite features is how it tracks sleep patterns and naps, because it helps you understand your baby’s routine better over time instead of guessing. Seeing when my baby slept longer, when they woke up, or when naps were shorter helped me adjust our schedule and feel more in tune with their needs. The heart rate tracking adds another layer of peace of mind, especially during those early months when every little thing can feel scary. Instead of constantly worrying, I could quickly check the app and feel reassured that everything was normal. The alerts are helpful without being overwhelming, and the system feels smart but still simple enough for everyday use. I also appreciated that it doesn’t feel bulky or uncomfortable for my baby, which was really important to me. Even during longer sleep stretches, the sock stayed in place and worked consistently. Over time, this monitor became part of our daily routine, not something that caused stress or extra work. It actually helped me relax more, sleep better, and enjoy my baby instead of constantly worrying. Whether it was nighttime sleep or daytime naps, I felt more connected and informed without hovering. For parents who want extra reassurance without complicated setup or heavy equipment, this smart sock feels like a gentle helper in the background. It doesn’t replace being a parent, but it definitely supports you, especially during those moments when peace of mind is everything. Overall, the eufy Smart Sock is a thoughtful, comforting tool that makes caring for your baby feel a little less overwhelming and a lot more confident. Read more

After owlet discontinued the support for older socks, we were faced with a decision I wasn't expecting. After some research we decided to go with eufy, and I'm SO glad we did. We have been using this every night for about a month now, and so here's the in-depth review I wished I could have had at the time I was looking. The sock design is so much better than other ones out there. I have no struggles putting it on since the sensor goes right on the top of the foot. Super simple. I also personally have not had any issues with the sock part being super worn or falling apart either, though she only wears it at night. If it does happen to come off for any reason, the base calmly tells me and there's a little image that lights up. It is so much better than the blaring music of previous products I've had. I personally rely on the base rather than phone notifications and I've had no issues. You can turn off the notifications it does if you want to keep it in baby's room (since it does charge it). It is wonderful for peace of mind, but it does so much more than that. It tells me how good my baby is sleeping, when and how often she woke up, her heart rate, her oxygen, if she's moving around, and how much sleep she got overall. I have my daughter in a mini crib a few feet away and this wonderful base has an image that lights up when she's wiggling, and will stop when she stops. It has helped me not get up every 5 seconds to check on her when I hear noises, making my sleep so much better. I have not had any issues like other people have reported regarding the oxygen sensing. It has never been suspiciously low. The oxygen sensing is in BETA testing so it will NOT notify you if something weird happens on the oxygen front, but you can always look at it in the app. It will notify you of a drastic heart rate change though. I would suggest going into the app settings and changing the heart rate notification parameters a bit so you get an earlier notification if something starts going strange. I love the app. It is simple and straight to the point. You can also invite other people (dad) to have access to see what's going on and be notified as well. The only issue I've had is the sock not charging from putting it on the base a tiiiiny but off. It will make a noise when it starts charging so make sure you listen for it. The battery life is a little over 24 hours, so I have used it on low battery a second night and the base will tell me calmly when it's about to die. For the price, I am so impressed. I would get this over other monitoring systems out there, especially if you can use HSA or FSA funds. Love it so much. So thankful. Read more

Anxiety Killer!!

I don’t care what anyone says these socks are great for peace of mind. I’ve had MULTIPLE false alarms, and yes it’s scary, and I’ve ran into my babies room and scared him awake because I was in a panic. Typically there was lotion on the sensor or we didn’t have it on right. However, I would do that every night rather and not be aware my little guy needs me in his crib and I didn’t know it. There are multiple size socks, the base is small and loud!!!, it charges to full in like an hour and half, and my baby doesn’t even know the sock is there. It has different alarms, low HR and, sock is being work incorrectly. It does NOT alarm for low oxygen. I have no recommendations between this one or the other popular sock because I never had the other one. If you are on the fence, just get one! Read more

Amazing but charging sucks.

It’s amazing for a peace of mind. It tracks his breathing, heart rate and even how long he sleeps. Only issue is the charging! Sometimes the sock just won’t charge even after being plugged in all day. Good quality and easy to set up but just annoying when it’s bed time and somehow the socks dead. Read more

Great value! Works really well!!

Great product. We used it for our baby til around 6 months. Honestly - I couldn’t sleep without her having it on in the beginning. It calmed my anxiety. We didn’t have the money to buy the more expensive brands but I’ll be honest - you don’t have to buy the expensive brand. This does it all and has real time updates!! So if you wake up panicking it was such a big assurance for me! Highly recommend. The sock options all fit perfectly, it’s very accurate and so easy to put on for babes. She never had any skin irritation or issue around her foot from the sock and they lasted the full length of time we used it. I’ll probably use the same one for my second! Read more
