From my side:
I find the stroller too low to go up 6 years of the child (as shown in the box).
My daughter 3 years and has a standard size. I think she is already looking a bit to "drive" his stroller.
Lying or highchair version the child is squatting or assi.
I do not know if that will go further than its 4 years.
The stroller a little noisy even with the lowest volume.
He missed a few colors (other than pink).
To improve this toy should be provided that the handle is telescopic to use the stroller for longer.
Change the colors a little (too pink).
