Aw, they really grow up so fast!

Teen Mom star Catelynn Lowell took to Instagram to share a sweet picture of her daughter, Novalee, and shared an exciting milestone in the two-month-old’s life — she took her first plane ride!

The proud mama, 23, captioned the shot, “Novalee’s first airplane ride! Let’s hope she’s good and momma will be happy! But if she’s not then oh well deal with it people.”
