The brood of TLC’s long-running reality series “19 Kids and Counting” keeps getting bigger, and so does the size of the show’s audience.

On Tuesday, the season premiere of “19 Kids” drew its largest audience to date, teaming with the best-ever season premiere for “Little People, Big World” to lift TLC to No. 1 for the night among cable networks in all key female demos.

Originally called “17 Kids and Counting” when it bowed in 2008, the TLC series averaged a best-yet 3.29 million viewers in the 9 o’clock hour Tuesday, more than double the audience it drew with its summer finale on June 10 (1.59 million).

In adults 18-49, “19 Kids and Counting” (1.4 rating/5 share), whose premiere picked up a few months before Jill and Derick’s wedding, was television’s No. 3 program for the night (behind NBC’s “America’s Got Talent” and a “NCIS” repeat on CBS). In women 18-49 (2.2/7), it topped everything on television Tuesday.

Following “19 Kids” on Tuesday, the 10th-season premiere of “Little People, Big World” drew the show’s largest audience for a season opener (2.075 million). It did a 0.8/3 in 18-49 and led cable for its 10 p.m. hour in women 18-49 and 25-54 (1.3 rating in both).

Elsewhere Tuesday, the second night of two-part original History movie “Houdini” did a 0.72 rating in 18-49 (down 23% from its Monday premiere) and 2.66 million viewers overall (down 28%).
