Kids are so interesting and they don't really make sense like Avian is pretty much passed out in the car but we just got home so all I do is bring him to his crib and sing songs and rub his face and he refuses to go to sleep and then on top of that he stays up for another 3 hours. Like how does a kid go from just passing out one second and the next wide awake. Where do they pull all that energy from when they were just exhausted two seconds ago? Think you would need sleep to get energy back!? Just frustrating like you have one small window to get your kid to bed and if you miss it you're screwed. He definitely would have slept a good hour or two if I let him pass out in the car. :/
