DS is 2.4. We haven't had a pushchair for him since he started doing outside walks, the grand idea being that he would get used to walking. This has backfired spectacularly as I usually end up carrying him around. I'm now 5 months pg and he is too heavy for me to carry over anything other than a short distance. I also know that I won't be able to carry him around when the baby arrives!
How do I teach him to walk vaguely sensibly? If he doesn't want to walk he will wrap his arms around my knees and wail until I pick him up. If he does want to walk then it isn't in the direction we need to go in and he is not past bolting off in a carpark or towards a road. If I put reins on him (tried both back-pack style and traditional) then he crawls along the ground like a dog 
What do I dooooo?!
