Omg I’m so sick of this 🥴

I love breastfeeding my daughter ! I think it’s great she’s getting her nutrients and it’s pretty easy for me up to this point and great for bonding(child finding comfort in you) but mannnnn I am so sick of it, she’s 20 months old and I feel like she’s still constantly on the boob ! Omg 😳 like she barely eats her food and then 15 minutes later she keeps asking for milk milk milk , or when we’re out she keeps asking for milk and I can’t just pull my boob out in the middle of Tesco she’s nearly two, i am going insane 😭 like for her age she shouldn’t be on the boob all day and it’s affecting my ability to do anything (or so I feel like today I’m so annoyed ) how do you wean ? Please help, my daughter is very demanding and I am parenting alone so I always give in, I can’t have anymore stress in my life my head hurts 😅😂What’s the easiest way to get her to leave me alone and start eating normal food ? Thank you
