So I have a bit of a catch 22 situation. My lb is 22 months old & he's reached a point where if he naps during the day, he won't go to sleep at night meaning he's grumpy when I wake him for my mums/nursery because he's not getting enough sleep & this is making it difficult to keep a routine. Now he will go all day without a nap but only because he's quite persistent himself! Around 5ish he's obviously shattered. Has anyone experienced this? How did you deal with it?
