Well, yes in that case the visa can be requested and obtain if dad has got the visa, travelled in the past so he can request for his son/daughter visa though my Younger brother was refused in oct when my parents applied for him.
Its not about 2nd application.
Kira was refused in 1st attempt alright but Embassy can take as much time as they want in processing your application either this is 1st ,2nd or many times.
What ever you did with application is done now. Application is under process so just relax and wait for thr decision. Try to enjoy the waiting game as most of applicant on this forum experienced.
Honestly speaking i never seek any kind of help from lawyers or never in touch for my visa process. I did everything on my own, with little help from this forum and from cic website.
