9wo ds has lost his voice and sounds like a very quiet cat when he cries. It's not loud enough to wake me up at night. He usually wakes every 2-3 hrs. Tonight I only woke at 5.30am - he went to bed at midnight- and am so worried that he's been crying before and I've slept through. I only woke at all because he was coughing which is a bit louder. To make things worse I've got a horrible cold and my hearing's worse tthan usual and I'm knackered because we've been in and out of hospital with ds over the past few days including two consective nights where I didn't sleep at all. Short of staying up all night I don't know what to do to wake up. I feel so terrible thinking I've left him crying on his own and ill too.
