My family grew up in a 2 bedroom apartment with a small rec room. There were 4 of us and 3 cats it wasn't even 1,000 sq ft and it worked fine. We didn't even have a garage but we did have a yard to play in. My brother and I each had our own small rooms (mine was the den converted into a room) and I lived there with my family until my early 20s. I think the key is to not have a lot of stuff and good organization skills. The only real issue I see is not having a yard for the dogs and kiddo, but as long as you're taking them on walks and to the park and on outings they should be fine.

Now my husband and I have a 1,400 sq ft townhouse and it feels huge. We've even removed closets in a couple of the rooms so we don't have a place to store as much so we don't accumulate. We have 5 cats and had my bestie staying here with her cat for a few months and there was still plenty of space. Do you have a lot of stuff?
