We use the Arm's Reach Co-Sleeper. Our new baby is 4 months old. We have sex in our bed sometimes, but mostly we have sex anywhere private in our house. =)
I was an evil child. If my parents ever spanked me, I would turn on the water works and get what I wanted anyway because they felt guilty. Maybe they should have spanked me harder or not spanked and then been permissive. I don't know.
We do not spank. I despise forced obedience to humans, yet somehow my children do almost everything I ask. There's no secret. I treat them with the level of respect many people believe should be reserved for elders, and they treat me and other people with respect without us having to spank them to do it.
My oldest daughter wants to take down Monsanto. I don't think an obedient person would be capable of such a thing. =)
