Need perspective re: sleep

CA2006

I feel like so many people on here have LO's that sleep a decent stretch at night.  Not my DD.  She won't sleep longer than 1 hour at a time if she isn't in our bed with us (on us) and bedsharing was NOT in the plan.  She also won't sleep longer than 3 hours...ever.  It isn't always wanting to eat that wakes her either...gas/poop is a major culprit.  Then we have to change her and voila...she's awake It took almost 2 hours to soothe her to sleep last night b/c she was overtired.  But really, I have NO CLUE how to get to the end of the day without her getting overtired. She grunts herself awake all.day.long! Makes for short naps and overtired baby. 

I know I am not the only one, but sometimes reading these posts, it feels like it!
