My ds2 aged 3.4 has had a cold this week that seems worse at night. He's been waking up between 1-2 and has wanted me to stay until he's gone back to sleep which takes ages every time I think he asleep and I creep out he's awake and it starts again! Has also been waking early any time from 5.30 and then he's up for the day. Anyway tonight I said I'm going to go to bed at 9 tonight as I am so tired. He looked at me and said you're always tired lately are you sure you're not anaemic?!! I couldnt believe my ears and yes it has been me getting up for ds2 this week.
