mommies with 2 kids or more

Hey ladies this is my 3rd and last baby I always wanted to breastfeed all my kids for one reason or another I never did more than 2 months this is my last chance and I'm mostly pumping because it's just easier to feed baby will be 3 weeks tomorrow and I really really just want to breastfeed from my breast but it takes to long and since I have other kids I I feel like I just can't sit there for so long it's either my others are hungry thirsty or I gotta cook and have food ready for when the husband has to go to work. How do you ladies do it? I mean I do it like at night when the others are sleeping or if we are out like at my mother in laws where I can just sit and do it and not worry about anything. I really really want to succeed this time
