the flannels which are stamped ' not suitable for childrens clothing' is due to childrens pj's are treated with a flame retardent chemical (which by the way washes away after about 20 washes) so by law---because someone had a child injured or killed because their clothing started on fire- sued the manufacturer- so now any fabrics that manufacturers think might be used to make a child pj's put the warning on it to protect themselves-
if your country was not so (sue happy) we would not have to worry about all the stupid warnings on everything we purchase...but unfortunatly that's where things have progressed-
since the chemicals wash away after a while it really (to me anyhow) makes no sense-means nothing-
you can make kids clothes out of anything you want- just for crying out loud- keep them away from fires! any fabric will burn and or melt...and who really wants their kids sleeping in clothing saturated with chemicals?
