DS will be 16 weeks on Thursday and for the last week his sleep has gone to pot, for example last night he slept fine till midnight but then was up every hour.
For a few weeks prior to this he had managed to wake only once or twice a night and it felt as though the worst was over but it's now worse than when he was a newborn.
Is there anything I can do to improve his sleep? He seems to be waking between sleep cycles and can't resettle himself. He has also developed an aversion to sleeping on his back. I have managed to sort out a side position in which if he rolls he goes onto his back rather than his front but he will then wake as soon as that happens.
His daytime naps are an issue too in that he will only nap in a moving pram, a moving car or in my arms (and even then only after a bit of a cry). I could live with that though if he was OK at night.
