Help on reconciling seemingly contradictory evidence about fetal experience
I know close to nothing about the subject of self-awareness in fetuses.

But learning &mdash;and certainly interaction&mdash; can occur without anything close to human "awareness", as evident by the fact that systems without a brain (and even without neurons) can learn. Any system that can process and store information is capable of learning. Does your definition of awareness include anything more than this? Conversely, organisms with a very simple brain can display aversive behaviour.

For an example of memory without neurons, see the Wikipedia article on immunological memory.
For examples of aversive behaviour without a proper brain see Zhang, Lu, and Bargmann 2005 and Babin et al. 2014
