When did you start entertaining your baby with tv?

My 3 month old is so amazed by television. I noticed him watching whatever we had on intently. So, I decided to try a simple nursery rhyme show. HE LOVES IT. Whilst feeling the excitement I felt having found a new and solid way to keep him busy.....I realized.....screentime is bad for babies they say! Ugh! It's one of those things actually, we said we won't ever use tv as a tool with our baby but then in the moment you're so desperate for a moment of peace you completely forget how against it you were .... Hey??? Relatable?
