Can anyone suggest how to get my ten month old back to sleeping soundly at nap time without a fuss. For last few weeks he has cried as soon as going into the cot at naptime and stands as soon as I leave the room. I try controlled crying where I leave him for 5 mins, return rub his back briefly and leave, then 10 mins the same, 15 and so on. Its taking over an hour and its relentless. I feel like we are going backwards as he was such a good sleeper for so long.
