In September, Ricci chatted with PEOPLE and revealed that while daughter Cleo is sleep-trained ("a f---ing miracle," she joked), her son Freddie still prefers Mom's company during snooze times.

"The fact that I can put her down in her crib and she just goes to sleep when my 8-year-old still sleeps with me is amazing," Ricci said.

The first time she tried to sleep-train Freddie was when he was younger, "He screamed himself hoarse and started banging his head against the crib railing," which made her reconsider her approach quickly.

"But with Cleo, when we decided to try it and see how she would react to it, she just sort of whined for about seven minutes and then laid down, clutched her little unicorn and went to sleep," the Emmy nominee shared. "It was like she was ready and she wanted to do it, and it was right for her."

As for big-brother duties, Ricci said she pays Freddie to watch Cleo "for 20 minutes at a time in her little playpen," so she can get some things done around the house, and that "he is really helpful" with the baby.

"He can help me make a bottle. He can help me in the bathtub with her. It is really great," said the mom of two. "There hasn't been a lot of sibling jealousy or anything. That has been a huge relief."
