We've always had a routine but since moving to 1 nap she seems to never be tired. I wish she would sleep anywhere that long but 1.24 is the longest she's napped with 1 nap.
Mine has always woke and gone to bed sametime whatever nap hes had. Hes been having 2hours again lately i find aslong as he doesnt nap past two hes ready for bed for 7 and wakes around 6.30/7
Have you got a routine for bedtime and wake time? It sounds like she might be having too much sleep. I only say that cos the same thing happened with my son. When we stuck to a routine for a few weeks his sleep improved. I would start waking her at the same time every morning, capping naps to 1.5 / 1.45 and having a consistent bedtime.
