When I bought my first e-reader, I too was hoping to spend less time on my smartphone mindlessly scrolling through social media feeds and get more reading done. I had also just become a new mother and found myself in a position where I would put my baby to sleep and needed to stay with her in a darkened bedroom and I couldn't keep any lights on to read. I started to read e-books on my phone to see if I liked it and found that I finished more books than before, but my eyes didn't like the glare from the phone so I caved and got myself an e-ink reader, even though I used to be one of those paper books snobs. I initially thought I would only use the e-reader when putting my daughter to sleep but have found myself reaching more and more for it rather than lugging heavy books around. The benefits have been massive, I read more than before (I'd say I read a book a week now, rather than one every two weeks like before) and I also read during any spare minutes that I got. Rather than pulling out my smartphone while waiting for the bus or in the queue at the supermarket, I pull out my e-reader and read instead. I spend much less time on my phone, read more than before and am now at a point where I far prefer to get the e-book version of a book rather than a paper copy
I wish you and your new e-reader a new and happy life together!
