It doesn't matter the age. Babies, toddlers, wobblers, small or big kids. They tend to need a bit of space for their activities. Not all activities but some. And maybe those activities need to move to a space outside the home, whether that the garden, or the green area close to the house, the local pitch or playground. The main thing is, kids will adapt. My son definitely can't run loops around our place but he loves climbing on the sofa and sitting on a low windowstill to watch whoever is calling to the door. He'll be as entertained throwing a ball back and forth and he is in a giant soft play ball pit.
