Dbaby was 8 months when we were all sent to WFH in March. I worked full time with him here until the end of October. You just get into a routine. Our day was something like
6-6.30 wake up, bottle, breakfast etc
8 start work, 8-9 is a quiet hour at work with no phone calls so didnt have to worry about noise etc
9.30ish - nap time so he was asleep for morning work call at 10am. If another call was needed I would schedule it for 10.30-11 so hed still be asleep.
11-11.30 he would wake up
12-1 I took my lunch break while he was awake, made him lunch and spend one on one time with him
1-2 I'm back to work but others are on their lunch break so it's a quiet hour and no calls come through
2-2.30ish down for his afternoon nap, which would see me through my afternoon calls.
4.15 finished work! Make dinner, go for walk, do bed time routine. Logged back on to do any overtime needed when he was in bed for the night.
First couple of weeks were tough, then we settled into a routine and coped really well, I even got an unexpected promotion!
