My 5 month old daughter used to nap 2-3 hrs and sleep around 9pm at night, wake up once in the middle of the night and then sleep again till about 9am. The past couple of weeks she just naps 40 minutes twice a day, and that's after so much hassle, and then doesn't go to bed till midnight. She's overtired and I can see it in her eyes. I'm a bit worried as it's my first baby and I'm also feeling a bit clueless. Anyone have a solution that has worked for them? Thank you x
