Is it ok to force children to do things in a certain way? I get very annoyed when my kid does not listen to me. How do you deal with it?

I would never force kids do things my way if I know they're not being unreasonable. You should really try and be patient with your kid as annoyance makes them even more testing. For example, if my kid goes around throwing objects in the house, I either don't pay attention to it or pick the objects myself without asking her to do so. A little later she rushes back wanting to help mommy clean up. Eating is an issue sometimes when I want her to eat something and she refuses. I have realized the trick is to not ask her to eat and leave a plate for her. She comes on her own and gobbles up everything. I agree parenting can be testing at times but just hang in there :)
