Hope is played by twins Bayley and Rylie Crecut and Garcia explained that they will also feature in the second season.
The news comes shortly after the team behind Modern Family revealed that they are recasting the role of baby Lily.
Garcia suggested that the Modern Family producers had made the right decision, telling Entertainment Weekly: "You can tell those little girls weren't having fun. It just came across on screen. I think they did the right thing.
"Certainly you work with child actors and you know all the stories. But as a producer, you want to know that you're doing something good by having these children on the show. And I think any time it's so apparent they're not enjoying their time on set, [recasting is] the right thing to do. I applaud them for acknowledging that and making a move over there."
However, Garcia added that he has not had the same problem on Raising Hope yet.
"We've been lucky," he said. "Our kids have been having a blast and are always in great spirits and having fun and have bonded with the cast. And the parents are really enjoying the experience, so all is good over here as we head into the terrible twos. You can check with me again after season two, but we'll see."
Garcia also confirmed that he has been filming the twins during the hiatus, saying: "We've been doing a little bit of that. The parents have been filming some stuff and we got some stuff with Lucas [Neff, who plays Jimmy] and Shannon [Woodward, who plays Sabrina].
"So I'm going to get all of that footage and hopefully be able to incorporate all of that. The plan is to [use it] in the cold open of the first episode. I think that'll be fun for the audience to bridge the gap from the last time we saw her to now."
Raising Hope will return for its second season on September 20 on Fox.
