Does reciting Surat Az-Zalzalah at the time of childbirth ease delivery, and are there any legitimate supplications and invocations that can be recited to facilitate it, and is supplication answered at the time of childbirth?

"Surat Al-Zalzalah and the verses concerning Allah's knowledge of what is in the wombs should be written with saffron in a vessel. Then, water is poured into it to dissolve the saffron, and the post-partum woman drinks it and wipes herself with it. Alternatively, the same verses can be recited over water, which is then given to drink and used for wiping. Or, they can be recited over a woman experiencing labor pains. All of this is beneficial, by the permission of Allah. The supplication of a woman during labor is more likely to be answered because it occurs at a time of necessity."
