Jim Edmonds had a kiddie party with his and Meghan King Edmonds' three children at his new abode soon after he moved into the residence following the couple's split.
On Friday, the 49-year-old retired MLB star had documented on his Instagram Story his official move to their second, larger St. Louis mansion, which is still unfinished and contains dozens of yet-unpacked boxes. He later posted videos of his and Meghan's daughter Aspen, 2, and 1-year-old twins Hayes and Hart exploring the new house.
The children rode a kiddie vehicle down the enormous hallways and seemed intrigued about their new playroom.
"Little more room to roam," Jim wrote.
"Keep going, I'm following you! Good girl!" he told Aspen. "Watch where you're going! Watch where you're going!"
Wearing a Cinderella dress, the little girl also played catch with her dad and stepbrother in an Astroturf-covered basement baseball training room. Hayes also got in on the action.
The kids had their first meal at the new house. Jim also brought along his children from his two previous marriages.
The baseball player and Meghan, a 35-year-old former Real Housewives of Orange County cast member, called it quits last month after five years of marriage.
Jim had left the first St. Louis home that he shared with Meghan and their toddlers days after the breakup.
The couple's breakup has been increasingly messy.
On Wednesday, Jim watched his and Meghan's kids at their primary home while she went out drinking with friends and called the police to have them check on her upon her return to ensure she was able to properly care for their children.
Also amid their split, it was also reported that Meghan accused Jim of cheating on her with one of their children's nannies, Carly Wilson, who has called the allegations "completely false." Jim has called the matter a "rumor."
On Friday, Meghan posted a photo of Hart and Hayes and Carly liked the pic.
The breakup also comes months after Meghan revealed that Jim admitted to exchanging explicit text messages with another woman.
