My ds seems to get tired pretty quickly in the morning. He's grunting and griping before the 2-hour awake mark. He usually stays awake longer in the afternoons, though, many times for 3 to 3.5 hour stretchs (I'll put him in his crib at around the 2 or 2.5-hour mark and he's rolling around and playing, sometimes for an hour more). A catnap in the late afternoon is random now, maybe every 3 days or so. I just go by his cues.
I'm assuming he's just not a morning person, like mommy and daddy. :wink: Has anyone else experienced this?
