Our take
On this page
Our verdict
This is Tommee Tippee's 2.5 tog Grobag in the 6-18 month size, the tog the maker matches to a 16-20°C room, which is the range the NHS and The Lullaby Trust recommend. The listing describes a snug fit at the chest with room at the hips, and a zip that opens from the bottom for nappy changes. The Lullaby Trust notes that most sleeping bags are fitted by weight rather than age, so check Tommee Tippee's size guidance for your baby, and make sure the neck and armholes are snug so your baby cannot slip down inside.
The variant trap is wide: Amazon.co.uk lists the Original Grobag in several sizes (including 6-18m and 18-36m), in 1.0 and 2.5 tog, plus dual-tog and legged Steppeebag versions. This link is the 6-18m, 2.5 tog bag.
Safety checks
The listing says the bag is tested to British and European safety standards; The Lullaby Trust names BS EN 16781:2018 as the standard for baby sleeping bags, so look for it on the label. Do not add a blanket on top or layer two bags together.
FAQ
What should my baby wear underneath?
The Lullaby Trust suggests a baby grow with a sleep bag at 16-20°C. Check your baby's chest or neck and adjust.
What about warmer rooms?
Tommee Tippee gives 1.0 tog for 20-24°C. In hot weather, the Trust says a light layer or just a nappy can be fine.
