Bobby scored our Carling Cup winner on Wednesday to secure a fourth round home tie against Manchester City on December 2 and Robbie suspects the strike will provide a platform for the young striker to push on up the scoring charts.
"I am delighted for him," he said. "He has worked tremendously hard since he's come here and it is always hard to get that first goal.
"Once you get it, it is easier and hopefully he can kick on from here.
"He is a good lad, Bobby. Like I said, he has worked hard, but he is a bit 'busy' and needs a slap or two more off me and Carry! He is one of these people who is always happy and smiling, which is always good to have around the dressing room.
"It is just getting that first goal now for Helder," Robbie added. "You tend to forget that him and Bobby haven't played the majority of the games and have only been coming on in fits and starts.
"Bobby has played in the last couple of games and grown in confidence - I'm sure it will be the same with Helder."
Bolton Wanderers complete the three games in six days at the Lane tomorrow - a sequence in which the team are determined to at least remain unbeaten.
"Bolton have many great individual players who can turn a game and we know it is going to be tough.
"Before these three home games we said we wanted to win every one of them or, at least, not get beaten. That is what we want to do, the Middlesbrough game wasn't the best but I think we played well against West Ham.
"We've done well, we want to carry on winning and that is what we're going to set our stall out to do on Saturday."
Robbie Keane says he is delighted Bobby Zamora got off the goalscoring mark against West Ham and tips Helder Postiga to follow suit very shortly.
