u/Impossible-Stuck

Went through self service at the local Woolworths and realised when I got home that I had forgotten to scan two items total value about $9.

It was an honest mistake as I was trying to make sure my 4 year old didn’t run away.

Am I going to be on a watchlist now or something. I feel really guilty but I’m embarrassed to go back to the store and confess. What should I do?
