The star has a grueling schedule thanks to jobs including her daily BBC Radio 1 show, being a panellist on Celebrity Juice, designing her clothing and home collection and presenting one-off shows like Children In Need.
But she insists her family come first.
Speaking on ITV's This Morning, she said: "I think any working mum takes a step back and definitely thinks very thoroughly about choices [they] make. You become a bit more picky, I guess because you really want to make sure that you're home enough.
"For me, family always comes first so I do put my emphasis on being at home, I've got two step children as well so making sure that they're really part of our whole process and our family and then work fits around that."
Fearne, 33, and husband Jesse Wood, 38, are parents to two-year-old son Rex. Jesse is also dad to children from a previous relationship.
"I was 29 when I met my husband so it was quite an induction into being a proper adult and a parent but I love it and they're amazing kids and they love Rex and Rex adores them, he idolises them!"
Fearne told Eamonn Holmes and Ruth Langsford that both she and husband Jesse had busy schedules but they spent time planning to make sure one or other of them is always home with the kids.
"We do have to kind of get very organised and militant about who is at home, when and where. We're really lucky that we have help - my cousin is our nanny which is amazing and she's gorgeous and loves Rex - so we've got help in place but we are just super organised and then I just try and take a seat back from work a little bit when I can."
The star will host this weekend's Tesco Mum of the Year Awards, which honour ordinary mums who have achieved something incredible or inspirational.
