It is absolutely possible. Do not let her believe any (evil, um, well-meaning but ignorant) drs who tell her otherwise.
I lead mtgs for bfing support of moms of multiples. Of course, dozens of twin moms have come through our group in the past 5 yrs who have successfually bfed, including moms with low milk supply and moms of premies and even a mom who had one of the twins have a cleft palate.
Triplet mos are more rare, but I did help one mom who bfed her trips for 1 1/2 yrs. Her babies were born at 35 weeks and spent a few days in the NICU, but did not have trouble establishing bfing.
#1 priority, line up outside help. In this mom's case, her dh lost his job just before the kids were born and didn't find work for a yr. A blessing in disguise. Also her mother and brother lived in the next town. Her mom came by 2-3x/wk and her bro about once a week, to do meals and housework and hold babies.
Mom was able to provide 95% of the milk for the babies. She pumped a little here and there throughout the day to give each baby one bottle of 1/2 breastmilk, 1/2 ABM around 4 pm when her supply dipped. Her supply would be better when she could lie down for an hour or so at that time of day. She would take the neediest baby to bed with her then and her caretaker(s) would mind the other 2 while she rested or even slept.
After a few months one of the babies started to refuse the afternoon bottle anyway and that was fine.
Mom was not really able to sleep in a bed the first month or so. She would sit on the couch with her feet on an ottoman, U-shaped travel pillow behind her neck. She would have her big EZ2Nurse Pillow on her lap with 2 babies on it.

Next to her on the couch would be a Boppy for whomever was done nursing. Or that 3rd baby might be in a vibrating bouncy seat or swing. The Boppy would hold a sleeping newborn secure. Boppies are not good nursing pillows for MoMs tho.(mothers of multiples)
Mom had all her meals made for her and almost always had someone else in the house with her the first few months so she could go to the bathroom, take a shower, or go outside for some fresh air and exercise for a few minutes.
She bought 2 slings so she and her dh could each have one.
She used pacifiers, but did not overuse them.
One of the babies had reflux but she did not buy into the idea of bottles with thickened feeds. She held this baby upright after a feed for 1/2 hr or put her in the swing.
After the 1st month or so, mom was able to go upstairs to sleep. they had 3 cribs. One was in the parent's bedroom. they used it as a side car. Usually 2 babies would be in it and one in the family bed. They also had a recliner in the room in case they needed to get up to nurse.
After a few months, 2 of the babies started sleeping rather well at night so they put each of them in their own crib. They would each wake once to feed. This of course, would vary depending on babies' personalities.
After a yr, when her dh went back to work and Grandma was burning out, they hired an adult mother's helper to help at midday for lunch, getting the trips outside for a playtime in the yard and then down for a nap. This continues. The trips are now 2 1/2 and they have a 10 mo baby sister!
