But the young Manchester City loanee feels like he's quickly adjusted to life on Teesside and in the Championship and says he "feels like he's making progress every day".
Crucially, the teenager believes there's even more to come, a hugely exciting prospect for Boro given the young Norway international has already very quickly established himself as a hugely important figure in Rob Edwards' side.
Nypan hadn't played a single minute of senior football in England prior to his Boro arrival but has featured in every single Championship game since he joined on a season-long loan from Manchester City.
It was a transfer Boro hadn't actually planned for in the summer, despite Nypan having long been on the club's radar.
The teenage talent broke into Rosenborg's first team when he was just 15, which grabbed Boro's attention. They watched him, loved what they saw but then stopped their scouting missions.

Why? It quickly became clear that when Nypan did leave Rosenborg he would be joining one of Europe's biggest clubs. Put simply, Boro knew they didn't stand a chance.
And yet come the summer, Boro were earmarked as the perfect loan destination for Nypan by Manchester City after the Premier League club won the battle for the young midfielder.
Why?
"They trusted us," explained Boro's head of football Kieran Scott in a recent interview with BBC Tees.
That trust is built over time. Boro signed Morgan Rogers from City, who saw how quickly and impressively the now-England international progressed at the Riverside. And City have watched and noted from afar how Boro have carefully and cleverly managed a number of other young players.
It also helps that Boro's chief executive Neil Bausor has a close relationship with Brian Marwood, who is City Football Group's managing director of global football. And Boro's chief scout Ian Breckin also has close contacts at the Etihad Stadium.
"It's a compliment to us that they feel we can take players like that," continued Scott.
"We've obviously had success with Morgan. It's a little relationship that's building well.
"We actually stopped scouting Sverre because it got to the point where we just thought he was beyond us.
"So we were delighted when he went to City. Neil has a really good relationship with Brian Marwood, so I said, 'just try a little message, see what you get back'. And it was a positive message back.
"Their loan manager had spoken to Ian Breckin as well and said we'd be a good loan. They seemed to identify us as much as we identified the player, so it was good.
"My understanding is we were the choice. If I'm wrong I apologise but my understanding is they identified us.
"I think we have such a good track record with the loans over the years, and we've shown we will play good players even if they are young. Ben Doak, for example. It's good that City see us as that and hopefully we can keep doing that."
Crucial for Scott and Boro when it comes to loan signings is balance.
In the 2022/23 season, Boro's best players were temporary signings, which led to them all needing to be replaced when Michael Carrick's side missed out on promotion.
Scott vowed after that summer that Boro's approach to loan signings would change, but that didn't mean they wouldn't ignore the market completely. Instead, they would look to loan signings to add to and complement their own players rather than building their squad around them.
And there are different types of loan signings. Nypan, like Doak last term, is a game-changer and an option that's simply deemed too good to turn down when offered. But Boro also used the temporary market in the summer to add some experience, with Matt Targett joining from Newcastle and Alan Browne from Sunderland.
"I think loans are good to have a balance of," said Scott.
"As we move year on year we have a squad or nucleus of a group now, so we're sprinkling [loan signings].
"We've been guilty in the past of taking too many loans but now we have a good spine of our players, then you add Sverre. Matt Targett was a great addition. Alan Browne similar. They're giving us good options.
"And it's very difficult to buy everyone you want because you're talking £45, £50m if you buy every player for the level you need."
As for Nypan, his impressive start to life on Teesside led to a first senior Norway call this month, and he reflected on his start at Boro in an interview with the Norwegian press this week.
“I feel I have already taken some steps up in terms of fitness and have more steps to take,” he said.
“Demands are set and that’s actually nice. It’s very educational and something I needed. I’m learning a lot from it. It was something I needed and part of the reason why I went there.
"The Championship is probably also a bit underestimated with the physicality that is in that league. There are not many other leagues that are as tough to play in.
"You can see that by how many matches there are and how many average metres you have to cover."
Scott knew from the start Nypan - despite his age - wouldn't have any problems in the Championship.
"There were a few moments in his first performance that really stood out to me," he said.
"His willingness to track and make tackles and win the ball back was brilliant. He was making blocks in the 18 yard box and chest pumping Callum Brittain. It was brilliant.
"He's a bright player. Man City don't sign bad players. They've obviously seen something major in him to invest that kind of money and they trusted us. Hopefully we can send Sverre back there and he's playing for them next season."
