J.C.
To switch sides I would lay on my back and lift my children up onto my chest. I would hold there head securely with one hand and their body with the other and roll over. I would position them the exact same way I did with the other side. The only thing was that I had to make sure that the baby didn't roll off the bed. I solved this by putting a pack and play right up against our bed. It had a bassinet insert that was the full length of the crib. I then created my own co-sleeper by putting a blanket underneath the pack and play mattress and up and over the side. I then tucked the rest of the blanket under our mattress. This way if I fell asleep the baby would only roll into the crib. It worked for us and they never rolled into the crib. Probably not the safest idea, but it put me more at ease. You could purchase a co-sleeper, but I already had the pack and play.
