In 3.5 minutes! Dd was happy and smiley. Then calm and sleepy. But this was unexpectedly soon after last nap. I whisked her upstairs to change her and put sleeping clothes on but I missed the window and have just endured 10 minutes of over tired thrashing and crying.
Could be worse, I know. But it's all very well looking for signals but with my child I clearly have to anticipate them! She's 17 weeks.
