I only recently started to put my 4 month old son in these sleeping bags for bed, partly because we had a red hot summer and the other bags I had for him were 2.5 tog and too thick. I happened to see this Anais and Anais sleeping bag on an email from Mummy and Little Me and liked the look of it so ordered one.. I am over the moon with it! Very lightweight very soft beautiful muslin cloth material. I just wish I had bought it sooner!
