At 38" tall, Helena is around the average height of a 3.5 year old. Her seated height is 21"(measured when seated in a chair from the top of the seat to the top of her head). She has plenty of room to grow in the primary seat, and even more room once she moves to the Sit+Stand.
Helena is the right size to enjoy the second seat for a few more months. As she grows she can keep using it longer with the canopy retracted, or move on to the Primary Seat or Sit+Stand.
With no height restrictions, Helena has complete flexiblity to keep growing, and hop on and off the jump seat throughout her day. Unlike competitors, the jump seat never interferes with a full recline of the front seat or built-in bassinet. When she hops off you can stow the jump seat and turn your Entourage back into a single stroller in seconds! The Sit+Stand is rated from 2.5 years (with good balance and coordination) up to 50 pounds.
The primary seat has a VERY TALL canopy to accomodate bigger kids and a firmer calf support with a foot well. The Second Seat has a standard-height canopy that works for children up to around 3.5-4 years old and has a soft-sided calf support.
