Parker said: “You know you’re going to have ups and downs. You can’t play like we did at the start of the season all the time. We’ve had a blip, but now we need to put it right.
“We just do what we’ve been doing, but try and do it a little bit better. There’s still a long way to go and it’s all to play for.
“I thought we would have had a few more points than we already have. The last few games have been a bit disappointing, but we just need to keep going, knuckle down with hard work in training and put it right again.
“We need to get out of this league – that’s our aim. It’s a big game tomorrow then we have Dundee United to come.
“It’s in our hands. They’re going to slip up, as well, and we just need to make sure that it’s us that are top of the league at the end of the day.”
Hibs have Celtic midfielder Kris Commons on loan for at least three more matches and Parker admitted it is crucial they get the former Scotland international up to speed.
He added: “It’s early days yet. After two games, you can see a bit of the sharpness is not there. Hopefully, we can get him back to his best on Saturday.
“Kris has got experience and he’s a goal threat. I don’t think he’s had many shots, a couple of chances at the weekend. but he’ll be fine.
“If we get him in a position around the box, we know what he’s going to do.”
The Edinburgh side have also been running the rule over Sunderland left-back Tommy Robson, but Parker refused to say whether they are viewing a loan or permanent deal for the 21-year-old defender.
He added: “We had a game in training, but you can’t tell after one training session. However, he’s here for a few days, so we’ll have a good look him.”
