With no custom styling, the datepicker and all of it's text are extremely small, and essentially impossible to read.

This is because react-datepicker uses rem for sizing and bootstrap sets the font-size of html to 10px.
A quick fix is:
html {
font-size: 14px;
}
well done @Gazler
@hoodsy I think you should close this issue
