She’s officially in uncharted territory. Amber Portwood is currently expecting her second child (this time, a baby boy) and since she only has experience raising her daughter, Leah Shirley, the Teen Mom OG star is reaching out to co-star Maci Bookout — mom to nine-year-old Bentley and one-year-old Maverick — for advice.

“I’m so excited and I’m anxious. I’m nervous too because I don’t have a baby boy,” Amber told In Touch during an exclusive interview. “I don’t know how to clean properly. I’m gonna have to call Maci to know what to do.”

The 27-year-old couldn’t help but gush about her friendship with the fellow Teen Mom OG star, even revealing that Maci’s already given the soon-to-be mother-of-two advice on how to get rid of morning sickness. “God, I love Maci. That’s my girl. She helped me out during pregnancy with this lemon water thing, so that helped my tummy out a little bit,” she continued. “She’s such a sweetheart. I’m nervous about taking care of a boy and raising a boy, but I think it’s gonna be so fun. I love how I’ll have a little boy and a little girl now. That’s just perfect to me, honestly.”

Amber can’t wait to see firstborn Leah interact with her baby brother. According to the proud mom, her nine-year-old has even been “practicing” her baby-holding skills in preparation. “My beautiful booboo yesterday at my baby shower holding a little baby doll getting ready for little brother James,” she wrote on Instagram. She also exclusively revealed to In Touch that Leah is “so excited to have a little brother.”

The little girl is already a big sister to two-year-old Emilee, who her dad, Gary Shirley, and stepmom, Kristina Anderson, share. “She’s so good with Emilee, and I can’t wait to see how she is with James. She’s being so cute about it. I can’t wait. It makes me more excited, actually,” Amber continued. “Leah is so adorable. She sent me a picture the other day with her and this little onesie that said ‘Little Brother’ on it, and it was so cute.”
