Hi Sara, thank you for the great post! I have already commented on 3 posts, but I do not want to miss yours. I have already been very curious about what it is like to be a PhD student and a new parent at the same time. You have depicted it to be a challenging and much worthy life! It looks like you are really good at balancing life and work. In life, you spend more energy with families and also gain endless love and power from them. In work, you contribute more to your lab mates and then enjoyed an open and friendly lab environment. I do not think that you should be critical of yourself about whether this is multi-tasking. You are multitasking because you have to deal with all kinds of interruptions and switch of attention. What I want to say is that there are good interruptions and bad interruptions. You have such a cute little girl. Lovable interactions with families and inspiring interactions with co-workers are all good interruptions that will make you more energetic and positive. They contribute to your mentality and mind. In comparison, aimlessly picking up cellphones and unconsciously get controlled by technologies are not good ones. Therefore, I would propose that it depends on the tasks included in a multi-tasking and it depends on your goals (not just efficiency, but also love and a meaningful life).
By the way, if you are using iPhone. This is something I usually do when I am working. I do not need to delete the apps. They can be still useful when we are not working. I will go to General – Restrictions – Apps – Do not allow apps, to temporarily hide the self-installed apps, and unhide them after work.
