bullshit, no babies tighter than fuck, 1 or 2 babies it's still good, 3 or 4 really starts to feel loose depending on her also, 5 or more that shit is gaping like you can see inside without stretching her a bit first though they might just be sluts fucking every thing that's big not only dicks but other insertables like big stuff, women are total freaks sometimes and babies are an indicator if she's single. So yes more babies bigger hole since that is a softball sized object exiting "birth" a once asshole tight orifice, just using experience and logic here.
