@HilaryDuff on Instagram Story: "I'm finally getting around to showing you Luca's birthday surprise this morning because I've been a teacher today. Um, it was REALLY fun and it was a success and he loved it, it was no Nerf gun party, which is what he was going to have."

@HilaryDuff on Instagram Story: "Um, it was homemade fun and it really took me down memory lane and I think he enjoyed it because he wanted me to explain every single picture. It starts with him, me pregnant, him on his first day."

@HilaryDuff on Instagram Story: "All of us in the hospital and then he just gets bigger and bigger through his first birthday cake, I'm just going fast, not to bore you with our family..."

@HilaryDuff on Instagram Story: "All of our family photos, oh thank you Banks..."

@HilaryDuff on Instagram Story: "Then, we had to skip to our front door and I'm trying to think, he is turning six now already, I took him on a hike this day and we got a little lost, it was the LONGEST hike ever."

@HilaryDuff on Instagram Story: "There's Brady, this was mommy/son day at school, a trip to Hawaii that we took, in Mexico with Mike and his family."

@HilaryDuff on Instagram Story: "Then, jump over here, this is the day Banks was born and he became a brother, a lot of stuff in the mean time, this was his favorite Halloween costume EVER, he was Wolverine, @RealHughJackman, he loves you!"

@HilaryDuff on Instagram Story: " @MatthewKoma and I's wedding day and the year he finally discovered that he loved sports, THAT'S THE END!"
