She shared the family fun day pics alongside the caption, “Sweet Summer,” with an array of green fruit emojis.

The Poosh founder is expecting her first baby with husband Travis Barker. Along with Penelope, she is also a mom to sons Reign Aston, 8, and Mason Dash, 13, whom she shares with ex Scott Disick. Barker, 47, meanwhile, is a dad to three children with ex Shanna Moakler: son Landon, 19, daughter Alabama, 17, and stepdaughter Atiana, 24.

After she announced that they were having their first baby together during his Los Angeles concert earlier this month, a source shared with PEOPLE that Kardashian “is just beyond excited.”

“She had happy tears when she told her family. They have all known for a while,” they shared. “Everyone is so happy for her. Kourtney can’t wait to be a mom again. Her older kids are excited about the baby too.”

“Kourtney has been praying for this,” they added. “She has wanted a baby with Travis since they first started dating. They have been trying to get pregnant for almost two years. It’s been grueling.”

Speaking about their relationship, the soon-to-be mom of four previously told Variety that she values Barker and appreciates sharing aspects of their lives on her family’s reality series.

“It’s so sacred to me, and I am very protective of it. I think I’ve learned a lot of lessons,” she said. “There is a lot of us on there, and we’ve had such a good time doing it because we have such a good time when we’re together, but I definitely want to protect it as much as I can. But also, this is my life.”
