This shouldn't be hard but it is!
DD is 3.5 and DS nearly 2. The walk home is 15 minutes at adult pace. Currently I have DS in buggy and DD on buggy board.
DD wants to, and can, walk home. And I'm quite supportive of that! However, as soon as she gets off the buggy board and starts walking, DS who is fiercely independent wants to get out and walk too. But for him it's a bit too far, and although a very keen walker he has a tendency to wander off in the wrong direction.
So either way I have one grumpy DC 
I guess DS just needs to learn he sits in the buggy for some months to come, but I thought I'd post in case anyone had any clever ideas.
They both have scooters and DD would be delighted to scoot home, but again DS can't manage it yet.
Any tips?
