Human Factors
Vector put us inside DRUMM intersection which was 9;000 ft; MSL to be on path. We were given 'Maintain 9;000 ft. until established; cleared ILS Runway 35R.' At that time; we talked about Aircraft Y landing in front of us and the need to maintain one dot high for wake turbulence. We also had a decreasing headwind which necessitated a lower power setting that we also talked about. We configured early to regain the glideslope from maintaining 9;000 ft. until established. The Pilot Flying asked for flaps 40 to help be in the slot. Concentrating on Aircraft Y that landed in front of us; I failed to crosscheck the altitude when he asked for flaps back to 30 until I moved the flaps. At that time; we were at 402 ft. AGL. I should have directed a go-around at that time. Lesson learned.
