What Is The Best Way To Explain Breastfeeding To Small Children?

I have a seven year old son and a three year old daughter and I would like some advice on how to explain to them about breastfeeding their six day old brother. They have both been asking questions about what I am doing when I feed him and why I am doing it that way rather then like their aunts (who booth have three month old babies that get formula). I didn’t breasfeed either one of them because I had to go back to work right away, which I know now is a stupid reason, but I am now a stay at home mom who is breastfeeding and I don’t want to hide in my room or whatever every time I need to feed my youngest but I don’t know what to tell them other then that when mommy’s have baby’s they make milk and that the milk that they make is the best food for the new baby. I know that they are at different levels of comprehension, I just want them to be comfortable with the way that mommy feeds their little brother.

How Would You Explain Breastfeeding To A 4 Year Old?

I have a 4 yr old son and I am pregnant and planning to breastfeed. Eventually, no matter how much I try to stay in another room, he will “catch” me breastfeeding the baby. I think I should explain whats going on ahead of time so he isn’t too confused but I have no idea how.
