He has finally gone down. Moose, I have no idea what's up with him. He has been staying awake for 2 hours for a little while now, but he was definitely tired. Not sure if it's teething... how can you tell? He likes chewing on things, but doesn't seem in pain. It seems to be him only getting cranky when I try to get him to sleep - if I keep him up longer he seems fine, though he's definitely tired with the amount of yawning and eye-rubbing he's doing. I don't know. These bubs can be a mystery sometimes. How is Sammy going - poor baby .
