We have a cot with one side removed (because I can't lift him in asleep as I'm too short) pressed up against our bed. Our 10mo starts out in there and then moves into our bed for feeding at night.
The problem is that there is no real barrier. He once woke up, roamed around the bed silently (without triggering the monitor) and fell on the floor 😪. Now I go to bed when he goes to bed, read in bed or I'm super vigilant and hovering near the bedroom. I have the same problem during naps. It's just a shame that I can't spend the few hours when he's asleep doing something else.
How do other cosleepers keep their babies from rolling off without being in bed with them all the time? I wondered if bed guards would help - I think they might delay him but not stop him completely.
My dd had a cot that became a toddler bed when you removed the sides. She didn't have a side rail because I had read some scary things about children getting stuck in them and injured. I put an extra mattress on the floor as a soft fall area to protect her if she fell out. She did fall out a couple of times but was completely uninjured. She would (and still does) like to come into my room and cosleep with me and when she was young I would make the soft fall area next to my bed. She never fell out when she coslept with me though.
