Best baby purchase of all

These pajamas saved us and have kept our baby comfortable and in the same pajamas for six months, which is a crazy amount of time for a baby. My only complaint is wanting the next size up! Please make them, Dagsmejan! I don’t have a plan for what to put my child in next!

My boys slept great

Ordered it for my twins as summer pajamas.

During the first night they were quiet and not as sweaty as usual the next morning.

So they seem to like the pajamas. The fabric is super nice and soft and light (I have a Dagsmejan pajama myself) and recommend it.

Great product

The pajamas feel very comfortable and our daughter is visibly comfortable in them. The snaps close almost too tightly so they are not easy to open and there is a risk of the fabric ripping out. This has already happened in one place in our case (for this reason 4 out of 5 stars, otherwise we are very happy with the suit and its quality).
