Not only do they not die or turn into monsters, but it's also an important lesson on how to explore one's interest to occupy oneself!
I also wanted to mention the idea of including your children in your interests so they get to know you and spend time with you (and you get to do something you love!), but there was no good seguefor that.
Indeed! In my early childhood I had the great fortune that my parents' workplace was located next door to our family home, so I got to observe and bother them at work, as well as help out within my limited abilities (they ran a small engineering company, so e.g. folding blueprints and stuffing them into big paper envelopes). That taught me a lot of valuable lessons about life and work (perhaps not always in the moment, but it was at times useful to go back to those memories later in life, anyway), and it was great to feel a little in the loop, so it also taught me something about the value of communicating with your loved ones. If they had a rough week I would know first-hand and cut them a little slack for not having the spare capacity to deal with me being a brat :).
According to Wikipedia her kid is less than 1 year old. It's tricky to involve them in your interests at that age :)
I can just about get my 5 year old interested, but my 2 year old is more keen on pressing the off button on my laptop.
