My 13 month old is ill at the moment - with a sore throat. He hasn't eaten more than a few mouthfuls in 5 days. And his sleep, which before this illness involved just one waking between 7 and 7, has truly gone to shit. He's waking almost every hour all through the night and cries for ages each time and then will only settle after I've fed him milk. He only wants me, won't be soothed by his dad, and it's killing me. However, my biggest fear is that he will lose the habit of sleeping well even when this is over. What's normal on this?
