You could get a truckle bed for your child (a smaller bed that pulls out from underneath the bigger bed) or you could get him one of those small toddler floor beds for showing CPS there is a bed-sharing alternative and also for yourself, in case sometimes you need to change up the sleeping arrangement!
@debbiedee You're a woman, you'll be fine. They're gonna side with you anyway regardless of your situation. And you're gonna get to collect a nice child support payment you can use for a mortgage payment.
