Can you tell me about fetal skull anatomy - what's the difference between adult skull and pediatrics skull anatomy?

Lots: Size, shape, grown areas bet see the flat bones in the skull, just to name a few. A child is not a miniature of an adult. There are lots of developmental changes that occur with maturation.

Pediatric skull: The first is the size of the skulls. The facial portion is 1/2 that of the adult skull. In a baby, it is about 1/8th. In an infant, the sections of skull bones haven't fused. This allows growth, of the brain and the skull. You can feel the baby front soft spot till the age of about 10-16 months, and the back until 3m. That's why Infant skull protection is important.

Adult / child Skull: Size is the main difference and after 2 years of age and once the fontanelles and sutures are closed, there is not much of difference in the skull itself. that is how the adult projection from child pictures is possible

Skulls : The skull of a child specially infants are smaller, there are fontanells & sutures between skull bones to allow for brain growth, if they close too soon as in craniosynstosis, the neurosurgeon will have to open the skull & insert a prosthesis, if the head is too big it could be hydrocephalus which requires a shunt to decrease the volume of ventricles. Pediatrician must monitor head size.
