weaning

I'm trying to wean my almost 11 month old from breastfeeding because it's gotten so bad to where he cries and pulls my shirt down in public and I don't usually care but I was in a very important meeting yesterday with my boss (who's a male) and my son was pulling up my shirt and crying and I was so embarrassed 🤦🏽‍♀️ and when we're home I can't get anything done, when I put him down for a nap and I try and pull away he starts to suck and pull even harder and it's so frustrating because he's asleep!! Lol at night it's pretty easy but during the day it drives me nuts !! I can't even get ready because he cries to nurse. Anyone have any tips on weaning?
