Black for Babies?

So what's wrong with the color black when it comes to babies.  When grandmas come into the shop, they sometimes comment on some of my black merchandise. The cable knit black cashmere cardigan from Lotus Springs..

The supersoft little skull cap in black...

The Maryjanes from Trumpettes..

Children shouldn't wear black they tell me. But why? So completely chic..

See you...
