My 10 week old is sometimes an arms in and out baby. Depending on his mood. This is great to work with and you can even do one of each. The fabric is beautiful and soft and there’s plenty of length and room.

Love these pouches! Have been amazing for my premie baby to when she was still too small for standard baby sleeping bags!
Excellent quality.

I am very happy with the cocoon swaddle bags. I bought them, because I wanted to transition my daughter from the swaddle to a sleeping bag. I was also looking for a good quality sleeping bag as I was using another popular brand before and the quality was rather poor. Ergopouch quality is so much better, it’s such a nice material inside, so the baby is kept nice and cozy. It’s a 2.5 tog and it gives me impression that it is thicker than another brand. My baby legs were nice and warm last night while in the other tog her legs were always cold. I’m very happy and don’t regret switching the companies although I live in the UK and the order came from Australia. Deliver was extremely fast, as if it was coming from the UK. I highly recommend them over LTD swaddle. By the way- it was her first night in the cocoon with arms out and she was sleeping so well in it!
