My DS is 28 months old and we have spent the last 6 months tweaking his routine.
I thought the same as you when he first started refusing his nap, and was worried this was the end of the nap - well he's now napping better than ever, every day and for 2.5 hours sometimes!
To start with we were alternating no nap days, then he wanted the naps back a few weeks later. Then we started getting BT dramas so had to start capping the nap, then we moved into a BBB and this seem to help with BT and we actually found an EARLIER naptime helped - have you tried this?
How is she coping without the nap?
