- Vernefie M.Verified BuyerReviewingAdult Sleep Onesie AshI recommend this productRated 5 out of 5 stars2 days agoSo comfy – perfect for twinning!
I absolutely love the adult onesie – it’s incredibly soft, cozy, and perfect for relaxing. The best part is twinning with my 4-month-old, who’s wearing the baby version. Such great quality and comfort for both of us. Highly recommend!
- Maddy B.Verified BuyerReviewingAdult Sleep Onesie DaisiesI recommend this productRated 5 out of 5 stars1 month agoBed sharing perfection
I got this for my first Mother’s Day. I’d been looking for an adult onsie made of good quality materials and was so excited when this was released!
I bed share with my baby and breast feed on demand during the night and this has been perfect.
I still wear a breastfeeding singlet underneath as well as thick bed socks if needed and an hot water bottle at my feet and could easily add some leggings if needed also.
How ever we have a small heater in our room to keep the temperature pretty constant so I am comfortably warm with just the singlet, onsie and bed socks. We are in country Victoria.
The zip is easy to unzip in the middle of the night for feeding and to quickly duck to the toilet.

Use this so I don’t need to sleep with a blanket, keeps me toasty or I layer underneath. Great quality and fits great
