Certain activities during wudu

1. I was doing wudu when suddenly my mom called so I needed to give a pause for a few seconds and when I came back I did my wudu from where I had paused. Is that okay or should I had done wudu from the beginning? 2. When doing wudu, lets say when I was cleaning my ears I felt like I should had cleaned my hands better so I quickly cleaned my hands again and then again continued my wudu from cleaning my ears. Is that okay? Hopefully they were okay as I believe Islam is a simple religion and my wudu wouldn’t be invalid for such minimal reasons.
