Is she nursing? Or attempting to (pumping and all)? If she doesn't have one yet, the EZ2Nurse pillow is very very popular with MOMs (mothers of multiples).

Then, a travel pillow for behind her head, and a footstool. She can stay omn the couch all night, nursing and sleeping, with this arrgt. A boppy next to her for the 3rd, not nursing baby.

A sling or 2.
A swing, even if she is APing.
Get her videos to watch, as she will get bored with regular TV. Take them back on time.
IMO, nevermind the coupon book. Cute, but she literally won't have time to rip one off and call you. Just make a schedule up for you to come over x times a week, at x o'clock. She will need
everything done for her.
She will only be able to sit on the couch and nurse pretty much 24/7. She will need you to bring a meal, warm it up, put it on a plate and serve it to her with a huge glass of water.
She will need you to hold/entertain all 3 while she goes to the bathroom or takes a shower.
She will need you to hold/entertain 2 at a time, when she goes upstairs to take an afternoon nap with one of the babies (the neediest, nursiest one).
She will need you to hold her while she cries.
She will need a foot/shoulder massage.
She will need a helper for outings for at least 3 years.
Don't forget about her after the first few months! If you can't do all of the above, find her someone who can, or several someones. Try a Senior Center for surrogate grandparents, or a church, even if she is not a member. Try the early childhood development class of a college.
