Outgrowing our shell

As these two kids of ours continue to grow and get bigger our two bedroom condo just keeps getting smaller and smaller. I feel like we are four hermit crabs fighting for space in one tiny shell. And these kids are growing really fast, especially the little guy who gets fatter by the hour! So what to do, as I've mentioned before the burbs are looming somewhere in our future but we would like to stay in the city as long as possible, and I just don't know if it makes sense to try and move into a three bedroom condo or townhouse for a short period of time. Or does it, I mean I really can't move an inch in this house without stepping on a squeaky toy, a doll of some sort, or tripping over an exersaucer. These two tiny people have accumulated a lot of stuff, which is in desperate need of some sort of playroom or separate space. For now the giant baby boy is living in our room with us, but how long can that go on for? With his pack and play set up right next to our bed, which is very convenient for the middle of the night feedings, I have about six inches of space to get through on my way into or out of the room. Which inevitably leads to at least 3 or 4 stubbed toes a week, especially in the late night hours when I can't even scream bloody murder like I'd like to. The next logical step would be for the two little ones to share my daughter's room, in all its lavender glory. Why should I care if the little guy has to live in a purple room for a little while, I know he won't know the difference, so why does it bother me. I spoke to my dad about it and he reassured me that we really don't have it so bad at all. He told me when he was growing up he and his two sisters had to share a room while my grandparents slept on a pull out sofa in the living room. But he also told me that he had to walk five miles to school uphill both ways through blizzards and hurricanes, so who knows. I guess we will just do whatever we have to do.
