Baby skin care

I know how to care for adult skin, but what about baby skin? 

As far as I understand, baby skin apparently contains more water than adult skin? Also, its acidic lipid barrier is not yet fully developed, which makes it a lot more susceptible to TEWL, dryness and irritation. So in essence, it’s very sensitive with a weak lipid barrier, right? Not sure about pH-level, though.

So my questions: 

Some sites recommend to use products specifically made for babies. But if I had a gel that contains 

and has a pH-level of 5,5, it actually sounds gentle enough even for baby too, no? Despite the phenoxyethanol, which I also found in many baby wipes. 

I initially thought sesame seed oil would be a good one since it’s supposed to be rich in linoleic acid and therefore more suited for sensitive skin. But I came across a post on sesame oil on your blog in which your sources say its equal parts linoleic/oleic, and hardly more moisturizing/occlusive than nothing at all…

Also, I once researched shampoo and came across a forum thread in which baby shampoos were discussed. One user claimed baby shampoo that says pH-balanced actually has a higher pH-level from regular shampoo because baby skin is still more alkaline and thus baby shampoo wasn’t as good for adult scalp?

Reading on the internet confuses more than helps, but I hope you can clarify a few points! Thanks a lot in advance!!
