Please help! My 9 month old usually sleeps well, 10-12 hours in his own room. 2 naps a day for 1 hour 30 mins. He's been waking at 8am lately so we've been aiming for 8-8. However the last week or so, after his second nap he is then awake for around 6 hours before he goes down for the night! He's tired but just won't sleep. He's not particularly whingy either, more hyper and playful. I don't really know what's causing it or how to get back to normal 🤦🏻♀️ I want my evenings back!
