The BABYDEEPSLEEP® Weighted Sleep Sack/Bag is a calming weighted sleeping sack/bag, designed for babies (8–12 kg) with agitation and sleeping problems. The patented weight section gently adapts to your baby's nervous system and whole body to provide calmness, which helps establish longer sleep cycles and calmer sleep.

The unique construction of the sleeping sack allows the baby to sleep on their belly as well as their back and ensures that the weight effect lasts throughout the baby’s entire sleep – unlike traditional weighted blankets, which are usually pushed aside.

About 85% experience "improved" or "significantly better" sleeping quality within the first 7–14 nights*.

* Quality feedback from more than a thousand families (2014-2020).

Safe to use

The weighted area covers the baby's chest and stomach, applying deep pressure to the body. This leads to muscles and body parts being stimulated, which triggers the nervous system. The nervous system interprets the pressure as a movement and responds by releasing calming and bliss-enhancing hormones. By reducing the baby's movement, the weighted bag contributes to a calmer, deeper, and more restful sleep.

With the extra-breathable bamboo and cotton material, you can use the sleeping bag with sleepwear or as a blanket. The weighted sleeping sack is 0.5 TOG, which is equivalent to a thin blanket.

Our BABYDEEPSLEEP® products are made out of extra-breathable bamboo and cotton material, which will prevent overheating. The weighted filling consists of small phthalate-free pellets, and the fabric and zipper are OEKO-TEX® 100 certified.

Tested in accordance with the EU safety standard EN 16781:2018. Non-lead and nickel-free. Recommended by health professionals and maternity nurses.

    I bought the babydeepsleep swaddle. And WOW. It was the perfect little safe place for my colicky son. We have a natures sway sling and the babydeepsleep swaddle was a perfect add on. During the day trying to get him to take a nap is much more peaceful and instead of sleeping only powernaps, he sleeps 2-3 hours. We are so relieved 🙂

    Maggie falls faster and deeper asleep and we do not have to rock her to sleep every night. She simply falls asleep by herself! Furthermore she now sleeps longer in the morning. Before she woke at 5 am, now she often sleeps until 6 am. AMAZING!

    I was a bit reluctant to buy the babydeepsleep suit for my son Thomas, because he is a very warm child. I wrote to the owner of babydeepsleep and after a few emails back and forth, I took the leap. I am NOT disappointed. The weight in the suit seems perfect for my son and it clearly helps him to relax more and fall faster asleep and sleep longer periods. The daytime naps are also longer and he wakes much more peacefully. The bamboo fabric is absolutely GENIOUS. I really love our babydeepsleep bag. We could not live without it.

Backed by Occupational Therapists and Used by Professionals

Unlike other baby weighted blankets, our blankets have placed the weight on targeted areas on the products rather than the entire products (nervous system registers the deep pressure technology better this way).

Babydeepsleep® products are some of the best products for babies with sleep problems. Offering babies extra comfort and proprioceptive stimulation is very effective.

Optimal Breathability

We are aware that restless little ones are usually warm. OEKO-TEX® certified bamboo/cotton fabric is used in all of our products due to its amazing features.

It ensures maximum breathability, temperature regulation and sweat absorption. An extra mesh insert at the top back is also added for extra airflow.
