All 3 young brothers and the toddler boy separate in bibs in front of a mirror (rear view) also in underwear in episode 3. Thanks again to db1 for pointing out this brief scene, I missed in 2012. Pic 1 showing the oldest boy, Eric (Matthijs van de Sande Bakhuyzen) ~10 yo. Jelle and Tim 8 and 7 yo even looking younger.
I previously had another boy and girl in bibs.
Still rating 4. Scenes are too short and dark lit. Good and funny series, though.
