My LG is 13 months old and she used to go to nap in her cot twice a day for an hour each time. I used to put her in the cot and give it 20 minutes and she would be asleep but the past week she has fought me for a nap at all. She rubs her eyes and yawns but after 45 minutes of her fighting sleep she finally drops off and only for half an hour! I don't know what to do. Is she ready to go down to one nap and why is she fighting me? Does anyone have any advice on what do?
