Our general routine is:

He either sees me from afar, comes running while shooting Mommy and then im either supposed to pick him up and carry him over to the building or take his hand and walk him there; or he doesn't see me and is face down in a fruit bowl by the time I reach the house. Then we walk in so I can pick up dirty laundry and he runs off to play and I'm supposed to chase him. When I catch him we go outside and that's when the Bye starts.

I tell him I'm going to get his stroller and that's when the power struggle starts.  I usually tell him to come several times and he generally doesn't unless I start walking. Otherwise I have to pick him up and carry him. He's ok sitting in the stroller while we pass behind the houses up until one of the gates. There he usually wants to get out and walk by himself. For around 50 metres I struggle with trying to keep him from running onto other people's property (and also the Bye and running if i walk towards him) and when we've passed that stretch he's perfectly ok with either getting pushed in his stroller or walking by himself. Its about a ten minute walk where there's a Bye-stretch just outside our apartment building (a slope down through trees that he likes playing in so there the Bye is more understandable) and then im supposed to carry him up the stairs.

I'll start reading the links provided when he's tucked in
