My mum was a fab knitter and also taught me as a child when I was rubbish at it, at 16 I knitted a baby cardigan and bootees for my pregnant sister that actually fit my nephew at age 2
I did do a couple of simple multi coloured blankets though which were quite good as nobody knew what size they were supposed to be
I tried again many years ago when I got married. I used to have to show mum a pattern to see if she thought I could manage it at first as I wasn't great at technical patterns but got better over the years. Mum used to knit all sorts of patterns, quite complex until the last couple of years when she couldn't remember them properly and would be forever pulling them out.
She used to regularly knit fancy baby blankets for a local group to sell for charity and was so frustrated when had to stop doing them. That's why I started the scarves, not something I usually knit, in hopes mum would try it. She didn't for a long time but then one day she just did.
Just cast on and then either knit every row, or as me and mum usually do k2 p2 which makes a nice ribbed one, when its long enough cast off.
Simple squares for a throw or baby blanket or bonding squares can also just be all knit rows so simple to do without having to keep track. A plain knitted blanket with a contrast yarn blanket stitched round the edge can look quite effective and very simple to do. Or if you have cotton yarn then dishcloths or facecloths are a good simple square project.
The hard part I know though is getting mum to engage with it. I think just try gently suggesting it a few times and if gets frustrated leave it for a while before trying again. My mum does do better at doing things when we are so maybe your daughters doing same thing will encourage her to try.
There's another full picture post for you lol
