Quoting Megan Durham Herman:" I plan on laboring as much as possible at home and dont plan on bringing my toddler to the hopital until ... [snip!] ... him or interact with him as much as possible to distract myself from contractions ( while still at home, not at the hosoital)."
It didn't hinder it at all for me, it started at 6am though so she was still sleeping and I didn't really accept it was true labour until about 9am. My SO came home by 9:30 and my friend was there to pick up my daughter by 10am. We were ready to go to the hospital by shortly after noon. Had him at 5pm. So it really depends on how quickly you progress, just have a plan with a couple back up plans in place and go with your gut!
