When I had 4 and pregnant with another (my youngest), I lived alone in a 5 bedroom, 3 bath home. (It was a repo doublewide.) My husband worked out of state for weeks and months at a time. My oldest was 8 and youngest was almost 3. I couldn't bear to have my kids scattered clear across the other end of the house. So I let them all sleep around me. I had a king sized bed. I laid in the middle on my side (usually left side) ...with one at my feet, one behind me, one in front of me ....and my youngest daughter draped over my pregnant belly. She'd say, "Can I p-p on you?" (p-p = sleepy) So she'd lay over my belly with her head on my side. And I'd rock front to back and rock the whole bed full of kids. (lol) And that's how we went to bed each night for months ...till my son was born. But all that to say ...it can be done. We didn't mind one bit. My kids needed that security at that time and it didn't ruin any of us. :)
