Constantly talking and back chat

I know it's obviously completely normal for a 3 year old to chat away. But anybody else finding it to be CONSTANT and non stop? It's the back chat that comes with it too?! Example 1. Freddie knows I can log into his nursery app to check on his day. So when I asked him the other day 'what did you have to eat today?' he replied 'dunno mummy why don't you just check your phone'. Example 2. He asked if we could go to the shops to buy toys, I said no it's dark everything is shut. His reply was 'well you're lying to me because I know Tesco is open until midnight'. I was not expecting this sass so young 😂
