I just cleared out the cupboard of outgrown baby stuff and came across some pure knitted silk long sleeved pjs I used for dd1 who had nasty, all-over eczema as a baby. Knitted silk is great because it doesn't irritate the skin at all and I found it very effective for dd.
They're in v. good condition, with a unisex b&w pattern. Size is 12 months I guess (no labels for obvious reasons!), but you could roll them up.
