The Sleep Suit Bag should be fitted around the neck and the armholes to avoid your child slipping through. In 'legs' mode, there should be enough length at the end of the suit to allow your child to move their feet freely. 2.5 TOG and 3.5 TOG Sleep Suit Bags should not be used in a 5-point harness or car seat for safety reasons.

- Brodie L.Verified BuyerReviewingJersey Sleep Suit Bag 0.2 TOG PebbleI recommend this productRated 5 out of 5 stars1 week agoPerfect for active little one
We have been using ergoPouch since our baby was born last year in August. It was time to upgrade to a sleep suit as he is very mobile now! He is able to climb down off the bed and walk, even if the legs are a little longer at the moment. I think he was pretty excited at his new found mobility in sleep, now that his legs are separated!! I honestly don’t think he sleeps the same when not in a ergoPouch. I sure know they help me.

Great lightweight sleepsack but already has a hole in it. So disappointed as we love Ergopouch products.
