Question to rotational players: is there a way to prevent currently not active families to get kids?

Just a quick update question on this one: is selling the double beds before leaving the household to play another one still the only reliable birth control?

Or has something changed in the meantime and somebody has discovered a better & reliable way?

If I understand correct we are about to get a proper way to control this with the next update or at least this is how I would understand what Kjun is saying in this update video at 1:28 [08.14.26] Focusing on the Little Things (Updated)
