My 4 week old has been up for the past 8 hours and I can't get him to take a nap. He is just super wide awake and looking around at everything. He fusses for about 2 minutes then just sits there and stares at me. This is so weird, he usually nurses then naps for 2 hours after. Could this be a growth spurt? I'm just loving on him as much as possible but he still won't get sleepy. I have a feeling I'm in for a very fussy night....
