BrickEconomy Member Review
“The LEGO Friends Aaliyah's Baby Sister's Playroom set is an adorable and highly detailed addition to the revamped LEGO Friends line. With features like a ball pit, high chair, crib, and rocking duck, the set captures the essence of playful sibling interaction. The standout is the tiny baby figure, Amelia, complete with a yellow onesie and a charming hat, as well as a collectible plush accessory. While there are many stickers to apply, they add personality to the playroom.”
Brickset
“Like the previous Friends' rooms sets, these are great sets to introduce the characters (or their younger siblings). Paisley's and Autumn's sets are packed with details that give insight to their personalities. I like that we're introduced to a new pet of Autumn's and all... More the musical theming in Paisley's. Aliya's baby sister, Amalia, has a really luxe playroom, especially with that ball pit.”
