guys, for real..

My child is the worlds worlds worst sleeper.  Some days I literarily day dream about being hit by a bus lol it's hell. I dread even the thought of ever doing this again but I've always wanted two kids but I can't imagine doing this with a toddler. 
What are your thoughts? 
I feel like this baby has ruined me for any excitement for having another. I'll just see it as sleep deprivation.
