Is it just me or there seems to be a baby boom in Hollywood this TV season? This is probably the 73rd post we've written here at TV Squad this year about a TV actress being pregnant, wondering how it will affect the show she stars in.

When the two lead actresses of How I Met Your Mother announced they were pregnant, the writers decided not to write the pregnancies in and go for the "hiding the belly under big clothes or things" option instead. They even shot the season finale months before they would have usually done so they could have the two actresses in reasonable shape.

People announced that Grey's Anatomy lead actress Ellen Pompeo is pregnant with her first child, while reminding us that Chyler Leigh, who plays Pompeo's half-sister, is due in May. We know that Shonda Rhimes decided not to have Lexie be pregnant but what about Meredith?
