ABC is leaving the Motherhood earlier than planned.

The network Monday said it was ending its Thursday night sitcom experiment a week earlier than planned, pulling “In the Motherhood” and “Samantha Who?” following the shows’ April 23 broadcasts.

That means “Ugly Betty,” which wasn’t slated to return to ABC’s lineup until May 7, will reappear on April 30.

“Motherhood” and “Samantha” have struggled mightily to find an audience in the 8 p.m. Thursday hour. Last week, the two shows averaged less than 5 million viewers for the timeslot, ranking a distant fourth in the hour.

“Motherhood” is considered a long shot for a second season. ABC brass are fans of “Samantha,” but the show has not been able to attract viewers when not behind a successful series such as “Dancing With the Stars.”
