DS has always been a great sleeper and has been putting himself to sleep with no fuss for bedtime and naps for months. He's recently cut his canines and they've all just about popped through but in the last week he's started getting really upset at nap times and refusing to sleep in his cot. He obviously still needs the sleep because he then gets tired and cranky and will fall asleep on us, contact napping. Night times, so far, have been fine. Any suggestions? I thought teeth because he does ram his hand in his mouth but because they've cut through I thought maybe not.
