My dd is 3.5 and loves her afternoon nap. When my 15 month old ds goes up she asks if she can go up as well. The only issue is now she is taking ages to go to sleep at night. She'll still be shouting and talking until 9.30pm. She's also waking early and seems generally tired and irritable in the mornings. Would you take this as a sign? Also can you let me know what you do to replace the nap time? I'd ideally still like to put in some quiet time for my own sanity as my dd is very full on most of the day.
