Aliya's Baby Sister's Playroom

This pretend-play toy set for kids aged 6 years old and up lets girls and boys create endless babysitting friendship stories. The LEGO® Friends Aliya’s Baby Sister’s Playroom (42645) creative toy set comes with 2 LEGO Friends mini-dolls, a baby figure and lots of accessories for role play. Inspire kids to build the playroom, where Aliya and Liann are caring for Aliya’s baby sister, Amalia. There’s everything kids need to create friendship stories. They can feed the baby at the table – a clever flip function shows just how much mess a baby can make at mealtimes! When it’s time for a nap, there’s a crib for Amalia. Playtime is catered for too, with a slide, playmat, ball pit, a rocking duck ride and a cute plushie-style LEGO piece. Then the friends take Amalia for a walk in the baby stroller toy. Discover other building playsets (sold separately) in the LEGO Friends universe, with lots more friendship stories to uncover. This set comes with the LEGO Builder app for intuitive building.
