"Happy 1st Birthday mama", he wrote, showing off some seriously sweet décor that included giant silver balloons spelling out, "Happy 1st Birthday Dream".
In the super cute pic, Rob could be seen wearing his signature LA Dodgers fitted hat as he held his baby girl high up in the air over his head.
While Chyna, 29, wasn't seen in any posts from the fete, the Lashed Bar owner was with her daughter on Tuesday, November 7, and shared an adorable video of Dream taking some of her first wobbly steps in order to get a chicken nugget.
Khloe Kardashian, 33, and Kourtney Kardashian, 38, also attended the event, and the oldest out of the Kardashian/Jenner brood brought her children Mason, seven, Penelope, five, and Reign, two, along to the party who played with Dream. But even though most of the family was present, Dream's mom and Rob's ex-fiancée Blac Chyna was nowhere to be seen. Dream, who wore a matching black Adidas tracksuit similar to what her dad often wears, seemed thrilled with her gifts as she smiled from ear to ear while sitting in her pink Mercedes SUV. The family celebrated with two pink cakes for the occasion, one covered in the design of edible roses and another with an edible photo of the baby, who Rob shares with ex-fiancé Blac Chyna.
"Aunty KiKi & Dream", Kim posted another snap of her and her niece.
Dream will soon have three new cousins to celebrate milestones with.
Aunties Khloe and Kim celebrated with their niece. I can't believe you are 1 today! "I love you so much, handsome girl!" North and Saint are so blessed to have such wonderful cousins to grow up with. Her dad threw her the biggest party and the whole family was there.
It is reported that none of the Kardashians were in attendance.
