DS has always pretty much hated his cot & been too hard to settle in there so we've co-slept since he was about 5 months old. recently we turned his cot into a toddler bed & he's having his naps & the first sleep of the night in there. he's almost 16.5 months. he just doesn't seem to like any sort of bars (well, anything that gets between him & where he wants to be )
