The former Wolverhampton Wanderers midfielder scored for the second game in a row as the Royals recorded a 3-1 win at Sunderland on Saturday.
"December's going to be a big month for us and we've got off to a great start," the 31-year-old told BBC Radio Berkshire.
"There's a tough game coming against Cardiff, but another three points would see us right back up there."
Resurgent Reading are unbeaten in their past four games, a run which has seen Jaap Stam's side climb to 14th place.
That leaves the Royals nine points off the top six, which remains a reachable target for the club that finished third in the Championship last term.
"We're still looking back at games where we should've picked up more points, but we're playing well at the moment," added Edwards.
"We know if we're doing that, the results will come and hopefully we can keep the run going. We know we're good enough to be in the top six."
