Greg Garcia told New York Magazine that he wants the comedy to appeal to a "broad" audience.
"There are going to be people who are not going to enjoy a baby getting thrown up on," he said. "But they're not going to not watch the show next week, because they also really enjoyed the sweetness of Martha [Plimpton, who plays Virginia] singing.
"And then there are the people who don't give a s**t about the singing and the sweetness, and they're going to be talking about the next day, 'Hey, did you see that they threw up on a baby?'"
He continued: "There's a certain amount of spreading it around. It's life - nobody's sweet all the time, nobody's gross all the time. We just try to capture all of that. And then at the end of the day do whatever's funny and tells a good story. We're not always going to be gross, but if we feel it's funny, we'll do it. And we're not always going to be sweet, but if we have a story that we feel we've earned it with, we'll go for it."
Garcia also revealed that he may begin "ageing the baby" in the future.
"I've talked about jumping forward in time so that the baby is all of a sudden three years old," he said. "Because there's a lot more stories to be told with a 3-year-old than, say, the ages of eight months and two. I have three kids and it's been my experience that things get a lot more exciting when they start talking and have emotions."
