Teen Mom star Maci Bookout's son, Bentley, is growing up fast at two-years-old, but the single mom says she isn't ready to give him a sibling just yet.
As a new clip from Tuesday's Teen Mom episode shows, while Bookout appreciates boyfriend of 16 months Kyle King's help in caring for Bentley, she has mixed feelings about having King's child.
"Some days, I'm like 'Let's get married tomorrow and have another baby!' and some days I'm realistic," Bookout, 19, says. "I don't want to rush into things just because I feel like I have to have to have a family for Bentley. I don't want to rush it if I don't have to."
Hinting that she'd love to have a girl someday, Bookout says she frequently feels left out when her son (dad is Bookout's ex, Ryan Edwards) and King, 23, do guy things.
"I think they like each other more than they like me," she tells Us Weekly, noting that when she tries to interrupt their YouTube viewing, "Bentley's like, 'Mama, we're watching dirt bikes!' I feel left out sometimes!"
Watch Bentley's adorable play date with Kyle above and check out the full episode of Teen Mom Tuesday at 10 p.m. (EST) on MTV.
