My sister’s husband is a web designer and he works mainly from home if he’s not meeting clients. She’s a stay at home mom and they have one son. She recently started doing gigs on Fiverr and her sales started picking up and she became very busy.
I am not sure how they’re doing it, but they seem to manage pretty well with the kid. They have a babysitter at the moment because their son is on summer break so it seems to work just fine.
Otherwise, when her son goes to school she has the whole day to do stuff and her husband has a home office, so they’re not really in each other’s face all the time.
