Breast feeding question

Estack80

So I am only 12 weeks but this will be our fourth child.  My first three I always tried and was never able to do it. They weren't getting enough losing weight so I would try to pump and then I would lose my mind with that so eventually would have to stop.  I would really like to try again this time but some people are already saying why do you want to put yourself through that again. Any thoughts or suggestions?
