When does everyone stop sterilising bottles

I stopped at 8 months cos she eats off the floor and all sorts now 🤣🤣🤣

They say after a year old, I still choose to sterilise Caitlin's now x

They say when off formula xx

I stopped at 10 months when little man went into cows milk. I never sterilised his bowls or spoons though xx

I will when my little girl goes onto cows milk after she turns 1. Still need to whilst using formula.
