Happy birthday, Lincoln!
Today Kailyn Lowry and Javi Marroquin's son turns three years old — and it feels like he was only born yesterday.
Both Teen Mom 2 stars took to social media to mark the milestone.
"My early mornings and long nights continue to be the best parts of my day. I love you Linc! HAPPY BIRTHDAY!" Javi says on Instagram.
Kail shared this adorable photo on Snapchat this morning, featuring her six-year-old son, Isaac, from her relationship with Jo Rivera.
"Good morning birthday hugs," she writes.
