I've noticed that when you ask HVs for any advice around sleep or feeding, they just repeat the same official blanket advice. I.e. feed on demand, sleep on demand. No sleep training in any form until age 1. And when I ask anything about timing feeds to facilitate better naps, or sleeping better at night, or encourage more efficient feeds with longer gaps in between, they just say something like "babies like to eat like us - sometimes they want a snack, sometimes a big meal". Every single time. I can't get any nuanced advice out of them at all. They just parrot the official NHS advice and refuse to tailor it in any way to your situation.
Was health visiting always like this? I have relatives who were HVs in the 80s and they always give me a really wide variety of in-depth, nuanced advice. But HVs now just sound like they're reading from a script. It's like they're just aiming the advice at the lowest common denominator of intelligence and are scared that any nuance runs the risk of babies being starved or neglected.
