Ditto, ditto ditto! In winter bub wears a cotton singlet with the bonds wondersuits, (which I believe are at least partially cotton based?). Then bubs just has an organic cotton double-lined sleeping bag to cover him. I have found a sleeping bag to be the most important factor - as any rugs you put on them come off soon after as they wiggle around so much!!
If you google companies like natures child, eco child, ecobabe etc you will find plenty of 100% natural sleeping bags and sleeping suits made of pure, breathable materials such as cotton, hemp and wool.
A couple of people bought us those thick poly suits for bub and apart from not allowing bubs skin to breathe, they don't allow enough room for the feet! The bonds wondersuits are by far the best fit and have plenty of room for growing feet!
