Mike Ruddock's side got their campaign off to a flying start, running in four tries to beat Scotland Under-20s 34-7 on the opening weekend.
However, the Welsh were next to visit Dubarry Park and left with a hard-fought 16-0 win before England Under-20s beat Ireland 33-9 at Franklin's Gardens.
Sitting fourth in the table, they host Italy on Friday night before a visit to France the following weekend completes the championship.
And even though Ireland may have left themselves too much to do in order to claim the title, Abbott believes they can make positive strides towards the Under-20 World Cup.
"There is still a lot to play for in the final two games against Italy and France," he said.
"We are building towards the World Cup in New Zealand in the summer, so it is very enjoyable and exciting.
And the youngster believes heavy defeat in England was misleading, with Ireland's cutting edge lacking rather than their quality.
He added: "The scoreline didn't reflect the performances at all but they took their chances and we didn't."
