Don't worry Sue you are def on the right track i reckon! My DD is about 3 weeks younger than yours. We have a 'strict' bed time routine - bath, bottle, bed by 7pm - but during the day i just go on her being tired. She wakes up at different times every morning so i can't just keep her awake for 3 hours until it's nap time if she's tired! thats not fair! xo
