Reds Manager Danny Wilson gave his thoughts following his side's 1-0 defeat at home to Crawley.
"It takes a little while to get together and to get an understanding of the calibre you're playing against," said Wilson.
"The points are important and we have to learn quickly. Games are coming thick and fast.
"We have to make sure we're at the races for the next game that comes along and that's the Crewe game."
Dale Jennings' sending off was the turning point with the scores at 0-0 - Izale McLeod scoring the visitors' goal with the Reds down to 10 men.
"It was an important part of the game. It was going into the last half hour.
"He raised his hands. Was it violent? It's not violent at all. He's reacted to a very bad foul on himself.
"It was a very, very harsh decision. I have to say it was quite soft. It wasn't a violent incident.
"We've been dealt that blow. It's cost us the game."
The Barnsley boss has called for his side to be more composed in the final third but wants patience for his young side.
"I don't think we've worked their 'keeper enough," he added. "There were a lot of mis-placed passes and we lacked that composure in the final third.
"You've got to understand that. We have to make sure in the upcoming games we have that composure in place because that can be the difference.
"I thought Hourihane settled in well. Adam in goal had a good game. I don't think he had much chance with the goal but made a good save just before that. It's his first game so he's done well.
"Luke Berry's come in from the conference and made the step up."
Wilson will be boosted by the arrival of Leroy Lita for Tuesday's visit of Crewe, as the striker joined the Reds on a one-year deal earlier today.
"We need somebody up there who can make it stick and bring a bit of guile and experience," said Wilson. "It came back too many times today.
"With a bit of luck Leroy will bring that experience and his goal-scoring prowess.
"There's a possibility he will (play on Tuesday). We'll see how he goes in training on Sunday and Monday in training."
