Answer 1

Have you tried researching about wp_query?

Also here's a basic looping according to category :

$args = array(
    'post_type' => array('post'),
    'order' => 'DESC',
    'category_name' => 'test',
);

// The Query
$query = new WP_Query( $args );

// The Loop
if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();
            // Your custom code
    }
} else {
    // no posts found
}
/* Restore original Post Data */
wp_reset_postdata();

Answer 2

You need to replace the cat-slug with Baby Health slug.

For Simple Blog Category

<?php
    global $post;
    $args = array( 'numberposts' => 10, 'category_name' => 'cat-slug' );
    $posts = get_posts( $args );
    foreach( $posts as $post ){ 
        setup_postdata($post); 
        get_the_title();
        get_the_excerpt();
        get_the_content();
    }
?>

For Custom Post Type - Taxonomy

$wp_argu = array(
    'post_type' => 'prayer',
    'posts_per_page' => '-1',
    'suppress_filters' => false,
    'tax_query' => array(
        array(
            'taxonomy' => 'category',
            'field'    => 'slug', // id, name
            'terms'    => 'bob',
        ),
    ),
);

$query = new WP_Query( $wp_argu );
while($query->have_posts()){ 
    $query->the_post();
        get_the_title();
        get_the_excerpt();
        get_the_content();
}
