Up until a couple of weeks ago, my 7 month old ds would nap for 1-1 1/2 hours in the morning, 1-1 1/2 hours at lunch time and 1/2 hour at 4ish. Now, all of a sudden, his morning nap is 40-45 minutes, and his lunch time and late afternoon are both 1/2 hour at the most.
Any ideas why this is and how I can encourage a longer nap?
Cheers...
