How to tell if your baby is colic or just normal crying?

my hubby seems to think that our baby might be colic but i think she just has normal crying spurts at times when she is tired, hungry, etc…. so how do you tell the difference??
when you say cries for 3 hours… does this mean a total of 3 hours all together per day or 3 hours straight at one time?

Why do some people with autism have dysmorphic facial features but others look normal?

I work with people with learning difficulties and i’ve always wondered why two of the people I teach with severe autism have dysmorphic facial features, and the other people with severe autism look normal!

How does this work?
