There’s a scene where a young pre teen girl gets soap in her eyes in the shower and jumps out screaming, a male friend of her father’s sees her and she is upset. It only shows her back and from the shoulders up.
The goose eggs Amy acquires were abandoned by their mother when her nest was disturbed. It's also established that Thomas did not maintain much of a relationship with Amy while she was living in New Zealand.
The other comment is referencing a different movie, called “Fly Away” Amy has some anxiety and PTSD from the car crash she was in that resulted in her mother’s death.
