Back is unfortunately too short

The car itself is great, it is nice and light, can be quickly put together, and rebuild (if you then know how ...) It can drive well, super are the handles, which you can extend. Our daughter is sitting well in it, the only thing I can complain about is that the backrest is not long enough. Our daughter is 2.5 (it is already tall for her age) but they can not lean on his head, could therefore not sleep in it. Why only 4 stars. We use the buggy only when we go shopping, and she is tired then, and wants to be purely translated. For this he is absolutely fine.
