I was pilot monitoring. We were given a clearance to maintain 250 knots until advised. Upon reaching 10;000 feet we accelerated to 290 knots (our normal profile). I advised the Captain that we were given a 250 knot clearance...we discussed and I probed the Controller and confirmed we were given a 250 knot speed restriction until 14;000 feet. We began to slow down. I believe the cause of this is the fact that we have not been flying a lot because of COVID. I had been furloughed and brought back to the line and retrained. I believe if I had been flying more often than I would have been able to catch this lapse earlier or could have reminded the Captain once we reached 10;000 feet.
Air carrier First Officer reported a failure to notify the Captain that the aircraft's speed was exceeding the clearance limit during climbout. First Officer cited lack of flying as a contributing factor.
