I m a breastfeeding mother of my 11 month old kid. My 4 year old kid also ask for feed. What to be done

A. Very important that you stop feeding your younger one in front of the older one it’s not a healthy practice first of all because at this age of four kids understand everything and they’ll be stubborn so you have to stop doing it and you have to tell your older child that you are grown-up you do not need mothers feet what other food and feed you are getting is just enough for you and say it comfortably so the child does not feel ignored or left out
