Had a time where they refused to nap for a few days and then went back to napping?
Currently in this situation with my 20 month old DD.
Sleeps through the night pretty much 7.30pm to 7.30am but is refusing naps.
Her early evening night sleep was a pattern of sleep for hour and then wake etc. this may have gone in to 10pm? Then she'd usually sleep through.
She used to take a hour and half nap around lunchtime.
Anyone?
