It gets easier to tell the older they get. Siamese sables don't really have any shading as babies (this age) - more of a dark gray/born undercoat with some lighter frosted tips (is what they look like - but sables are born with dark skin, and sable points are born with pink/light skin). I bred sable & sable point Hollands (and shaded dwarfs), and almost always when a kit had dark gray shading like this, I turned out to be a sable point (usually not carrying rew). In Hollands, some sable points are caused by the cchd gene (so they'd technically be sallanders, but sable point is recognized, so everybody calls them that), which makes it even more common to see dark sable points in Hollands. I'm attaching a picture of a baby Siamese sable & smoke pearl for comparison (smoke pearl on bottom)
