The Twin Z Pillow is a necessity for a mother who is nursing twins!! It has been a blessing!! I have 4 children(4, 2, and 4 month old twins) and would not have had the time to nurse both babies separately. We have also figured out you can use this pillow for many other purposes such as a prop, support and pumping. Instead of having 2 boppy pillows I prop the babies up in the Twin Z. Now that they are sitting up some I use it as a supportpillow. Whenever I pump at home I sit in the Twin Z for the back support. I would also recommend purchasing two, one for the house and one for the car. My husband and I are always on the go with the other children and the other pillow is great to have for backup! Thinking back to nursing my older two children the Twin Z pillow would have simplified this task as well. I recommend this pillow to everyone I meet who are planning to breastfeed!
