We have now had a very quick trip through more than 9 months of development in nearly 2 hours. Before we finish it is worth thinking about times in development when things may go wrong.
Environment Effects
- These are developmental times (stages) sensitive to insult, be aware of these times, the causes and the potential effects.
Critical periods of development refer to times when genetic or materal effects can impact upon the developmental process. The timing of these effects will impact on different systems at different times.

Systems with long periods of development or complex developmental origins are more susceptible to developmental abnormalities.
- Which systems will take a long time to develop?
- Which systems are complex in origin?
Australian Statistics
Genetic
Fetal Origins Hypothesis
The Fetal period is also potentially sensitive to maternal effects that impact upon interuterine growth. Along these lines there is growing evidence that low birth weight, and therefore inhibited fetal growth, has postnatal effects on lifelong health outcomes.
