Monday hour 1 question

How do you do your Monday hour 1 scheduling when you have a 5 month old baby and naps are unpredictable and baby’s temperament is unpredictable? Before the baby I was GREAT at calendaring. Now I put things in the calendar for the day, rather than hour by hour to try to get everything I want done in the day, and I do it as I can. But it feels chaotic to not have a certain time that I’m getting tasks done. I’m just curious how to navigate this with an infant, and how to get the 2 hour focus time in as well.
