I like Lyndsey Hookway if you want a counter to this kind of thing :)
But in general, I would caution against consuming/seeking out too much parenting content on social media in general. I find that the short form nature of it tends to mean that a lot of it is overexaggerated, a small part of the story, or straight up false, because there isn't enough space/time for nuance or reference to sources, but because you're seeing the same thing over and over again there's a psychological phenomenon which makes you assume it into your general knowledge and then it gets treated like any other information that you "know", without you necessarily realising that it's come from a less robust source than, say, something you learned from a book or a course or a teacher or life experience or had looked up the official recommendation etc.
Also, the algorithms favour polarising content, so you'll tend to be bombarded with very one-sided viewpoints, often with criticism for the other side, often with fear bundled into it. So the sleep training type accounts will have loads of threatening warnings about "bad sleep habits" / you'll never sleep again or even claims that whatever you're doing is harming your child's development or increasing their risk of SIDS. And a lot of the anti-sleep training accounts will equate controlled crying with abuse or neglect, or speak about brain damage or trauma, or breaking your child's attachment if you ever let them cry, and in reality neither of these positions are true, but constantly consuming content that seeks to provoke anxiety really can make you anxious and worried about getting things wrong, and that's really unhelpful.
Lastly, even if you are really careful about which accounts you follow, I still think it can end up very overwhelming and not as helpful as you would assume. I thought I'd try and clean up my instagram and make it more useful so I followed a load of people that I think put out useful/good content, but actually even with this I find scrolling it is quite stressful, I think because I'm being bombarded by 25 different pieces of micro advice and it's just too much to process all at once. And when I've finished, I'm not left chewing over whatever I've learned, I've just instantly forgotten it all because it is too much random unrelated information.
So I think I'm going to go back to the balance that I have on facebook, which is much more manageable - a few RL friends and groups with RL people, some harmless fun/entertaining groups that are neither inspirational (guilt/envy inducing) or educational (stressful) and just a handful of learning type accounts on topics I'm interested in that I just don't have time to look for long form content or that person doesn't produce it but I like them anyway.
For parenting advice or anything else I do want to learn about, I will use instagram to quickly get an idea of someone's content, and then I'll look to see if they have a podcast or any books or a youtube account (with longer videos). I find that it's more effective to learn stuff this way, because in the same 10 minute period, rather than being fed 25 randomly unconnected facts, I can learn more of an in depth understanding of one topic, that's more interesting, more useful, it's more likely to be well informed and it will stick with me over the next day or so, so I can think about it, process it, maybe discuss it with somebody or try it out.
