Is it bad if i straight up ignore what my kid is saying at times?

My 4yo sometimes plays with the tablet. She mostly watches Netflix and images she asks us to look for in Google. Rapunzel, Elsa, etc. Basically pictures from the things she watches.The issue comes when she asks to look for a set of pictures, then 2 mins later comes asking for another set, 2 mins for another one. Sometimes she can get very specific wanting a picture of two specific characters in very specific positions (staring at a tree, dressed a certain way, etc) and the constant "daddy I want this" can get to me in the long run.I try to tell her that what she's asking can't be found, but she constantly replies with "but try" until I have nothing more to say and she ends up crying.Is it bad that when she comes asking "daddy, daddy ... Daddy" I just ignore her for a little bit ?/Rant via /r/Parenting http://ift.tt/2imZaw1
