Align flex children to top

Question

How do I get flexbox children to line up vertically to the top edge of each row?

HTML:

#container {
  align-items: flex-start;
  align-content: flex-start;
  display: flex;
  flex-wrap: wrap;
  justify-content: space-between;
}
.child {
  margin: auto;
  border: 1px dotted #CCC;
}
img, h3 {
  width: 160px;
}

<div id="container">
  <div class="child">
    <img src="http://via.placeholder.com/160x160">
    <h3>Title</h3>
  </div>
  <div class="child">
    <img src="http://via.placeholder.com/160x160">
    <h3>The quick brown fox jumps over the lazy dog</h3>
  </div>
  <div class="child">
    <img src="http://via.placeholder.com/160x160">
    <h3>Title</h3>
  </div>
  <div class="child">
    <img src="http://via.placeholder.com/160x160">
    <h3>Title</h3>
  </div>
</div>
