Is Dwarfism immediately recognizable at birth?

Can doctors immediately recognize an infant has dwarfism when it’s born or does it take a while to begin to see the signs?

most of the time, yes. 
When a baby is born, doctors can see the characteristics that point to dwarfism, like: a shorter than average neck, flattened cheekbones, shorter arms/legs but average size hands/feet. 

Doctors can sometimes diagnose dwarfism during the pregnancy as well, either by an ultrasound (they can measure the legs/arms and see it’s not at the right length) or, more in depth, look in the baby’s DNA.  Dwarfism, or achondroplasia, is cause by an inherited altered FGFR3 gene.
