My 25 week old son normally has half hour cat naps during the day and stirs through the night a lot! Last night he only stirred at 3,4, and then milk at 5 and slept until 6 now today he was in bed at 8 until 9.30 then fell asleep in the car at 10 until 11 and then was back in bed at 1 and is now still asleep at 2.50. Will he sleep tonight or not or is it a growth spurt?
