Question about p:nth-child(odd)

Hello everyone,

My question is about the difference between

p:nth-child(odd)

and 

p:nth-of-type(odd)

The CSS code below:

p:nth-child(odd)    {

    background-color: steelblue;


}

changes the background-color to steelblue for the 2nd paragraph, 4th paragraph, and 6th paragraph under Box1. I was expecting it to do 1, 3, and 5. Why is that?

But when I use

p:nth-of-type(odd)  {

    background-color: steelblue;


}

It changes p1, p2, and p3 which is what I expected.

HTML:

<body>
    <div>Box 1</div>
        <p>
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmodnth-of-type
        tempor incididunt ut labore et dolore magna aliqua.
    </p>
    <p>
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmodnth-of-type
        tempor incididunt ut labore et dolore magna aliqua.
    </p>

        tempor incididunt ut labore et dolore magna aliqua.
    </p>
    <p>
        Praesent vestibulum purus justo, vel viverra nulla porttitor ac. Curabitur laoreet 
        luctus erat, eu porta dolor lacinia ac. Nullam fermentum tellus nec neque gravida adipiscing at quis dui.
    </p>
</body>

Thank you for your help :)
