Just when I thought our sleep issues had got to a manageable point, ds has decided he will not sleep during the day. He is 18 months and clearly exhausted but just will not sleep. He plays, sings etc for up to an hour but no nap. But put him in the car and he's asleep in minutes.
We thought maybe he needed to move to a later nap but that was a complete disaster. I am at wits end. Any ideas?
