Me and DH have both worked full time since DD was 9 month.
She was 5yo and in yr1 when covid lockdowns happened, neither of us were entitled to furlough and we were in an enhanced lockdown area so schools were closed March - Sept, then closed again Xmas - Easter.
Despite that DD is high achieving at school, not attached to a tablet, socially adept. It's a cop out to blame Covid.
Yeah it was hard, we basically had to flex our shifts to do 2-3 hr shifts across 7am-10pm so one of us could be interacting with DD while the other was working. We explored all the local nature walks, grew a load of veg in the back garden, created schoolwork from online resources, turned the living room into a fort, did every craft activity we could think of, set up FaceTime calls with her friends where they basically showed each other their toys for 2hrs....
It is very possible to be an engaged parent even if you're busy.
