Older baby pulling shirt down to nurse 🤔

So my almost ten month old has always been a snacker and has always comfort nursed a lot and I'm fine with that

...but oh my goodness he's just figured out how to pull my shirt down and help himself!! Around the house I'm not wearing a bra and it's hard to stop him! Lol I'm not sure how I feel about just letting him have at, and I don't want him to think he can do that in public 😱 not that I have anything against bf in public by any means just don't need him exposing me unexpectedly!!!

Does anyone's baby do this? 😫
