Someone is having a baby upon the return of "Switched at Birth" season 4 but no one knows whose baby is it. Just recently, Katie Leclerc, who plays Daphne in the series, posted a photo of a cake molded into a baby stroller. It was blue and the text on it revealed that the little one will be a boy.

Unfortunately, the actress asked the same question as the fans: "Whose boy is it?" Leclerc's Instagram followers bellowed into tons of speculations and suggestions but really, anyone could be welcoming their new son in the near future.

It could be Bay or Daphne. It could be anyone. It is extra difficult to tell knowing there are a lot of female characters in "Switched at Birth." Kathryn may even be the one having a baby as her essayer, Lea Thompson mentioned during a chat with E! Online new challenges of being a mother and a wife.

For now, the revelation of the identity of these mystery parents will have to remain a puzzle until "Switched at Birth" season 4 returns on ABC Family. Upon the midseason premiere, also expect troubles about money and breakups.

"There's going to be big financial problems with John and Kathryn and that's going to be really challenging," Thompson teased E! Online. "They're so used to being able to fix everything and being the mama and papa bear, but they can't this time and that's going to be really hard on them," she added.

Bay will also continue to struggle as she moves on from her breakup with Emmett. However, it looks like she isn't as attached as she used to and "Switched at Birth" fans may see her moving on. Unless of course she turns out to have a new son with her ex (some fans speculate she may be the answer to Leclerc's question). Moving on will be a problem.

"Switched at Birth" season 4 will be back on Aug. 24.
