Mistake I tier 2 online application form

Hello I've made up minor mistake on my tier 2 application form. I'm currently on PBS dependent visa. Can't file my application from UK so had to travel India. Did the application on 2nd December. I had a phone call from Bombay visa office to cross check my application. They asked me serval questions regarding my work salary Etc. In the end they've asked me about my family background as well. In that conversation I've explained that have baby of 3 months. But when I came home I've checked into the children section I've mentioned no child. I don't knw what to to. Would this be the ground that they can reject my application? Please do suggest me what shall I do next.
