super soft and comfortable

our baby sleeps very well in it, always has warm feet, but does not sweat, which was previously with other rompers always a problem, only small drawback is that the distance between the printers on the chest or abdomen is so large that when moving the belly is naked, still 5 points!!!

Super!

Our son sleeps much better in these pajamas. Only the snaps are not quite ideal because always some skin comes out. Would still buy the pajama set again.

Happy baby

I myself love my nightgown from dagsmejan - already in pregnancy and also when breastfeeding. My newborn also seems very happy in his pajamas.
