Something has already been said about the hallway and guest WC. I agree and would do it like Nordlys.
About the windows: Do they really have to be floor-to-ceiling? We had them in the plan at first too. But then we discarded the idea because of our furniture. If the couch is in front of it, the great big window is useless.
I would really avoid fixed glazing. You don't save anything compared to regular windows and a burglar would prefer to enter through the patio door anyway.
Then it might be an idea to reduce the children's rooms by 2 sqm each, leave out the hallway, and then shift the bathroom slightly to the right, enlarging the hallway and living room.
By the way, you won't want to put the stroller in the hallway. Why would you? You have a garage. The stroller fits perfectly there, and in winter, you can take the footmuff outside if necessary. We did that too and it worked great.
