Weirdly, it’s not age but an individual perception thing. Many many people don’t really notice or care about the needles (me included) because as OP parent posted, we have other stuff to deal with that takes up way more mental space. I guess this isn’t apparent because the needles are the obvious bits but then rest is all the “thinking” that invisibily surrounds the injection. There are however many people who just can’t wrap their head around needles and can’t do it. The needles themselves are tiny so it’s not that - it’s just how they perceive the world. Any technology that helps these people and makes their lives easier should be embraced.
