My DD dropped a sleep at around your DDs age. Its hard so big hugs!!! At this age they are going through major develpmental changes and it really disrupts their sleep.

If Em is showing signs of needing an extra sleep in the arvo I'll put her down and like Ruf will give her half an hour and get her up and just deal with the whinging!!!

If she is sleeping well at night she might not need the extra sleep during the day.
