When I was registering for twins, the Twin Z Pillow came up in every NICU parent group, every twins Facebook group, and every “what do I actually need for twins” Reddit thread I found. It’s expensive, it’s enormous, and people are borderline evangelical about it.
So I bought it. I also had two Boppies from before I knew I was having twins. I used both extensively in those early months, and I have opinions.
Here’s the actual comparison — not the one written by someone who tested both for a week, but the one from someone who spent a year feeding two babies simultaneously at 3am.
The Quick Answer
Get the Twin Z if: You’re nursing or bottle-feeding two babies simultaneously and you want one product that handles it. The size and design are purpose-built for twins.
Use two Boppies if: You’re predominantly bottle feeding, doing more independent feeding sessions, or you already have one or two and don’t want to spend the money.
Get both if: You can budget it. They serve different functions more than they compete.
Twin Z Pillow: What It Actually Is
The Twin Z is a large, C-shaped pillow designed specifically for twins. It wraps around your body and has two elevated sides that each hold a baby. It’s designed for:
- Tandem nursing (both babies at once)
- Tandem bottle feeding
- Supervised tummy time
- Propped sitting as babies get older
- A place to set both babies down while staying hands-free for a few minutes
Dimensions: It’s big. Like, takes-up-the-whole-couch big. Plan for it to live in your primary nursing/feeding spot because you’re not moving it constantly.
Weight: About 4.5 lbs. Manageable but not something you’ll carry from room to room constantly.
Cover: Zippered, removable, machine washable. This matters enormously when you have two babies who spit up regularly.
Price: Around $180–$200. Check current price on Amazon →
What I Actually Used It For
The Twin Z was my primary tool for tandem nursing in the first three months. Getting both babies latched simultaneously is a skill that takes practice, but once you have it, it saves significant time. Feeding one, then the other, then repeating is exhausting. Tandem feeding cuts the whole process roughly in half.
It was also genuinely useful for tummy time once my twins had enough neck strength to lift their heads — having both of them on it at the same time meant I could do tummy time sessions without losing one of them off a mat.
Boppy for Twins: Using Two
The Boppy is a horseshoe-shaped pillow most people know as a single-baby nursing pillow. For twins, you use two — one on each side, essentially creating your own DIY tandem nursing setup.
The pros of two Boppies:
- More versatile for single-baby use (and you’ll have one left when you stop tandem feeding)
- Better for side-lying nursing positions
- Each baby can be in a slightly different position
- Can be used across different spots in the house more easily than the Twin Z
- Less expensive individually (around $50 each, or ~$100 for two)
The cons:
- Two Boppies take up more overall space than the Twin Z and are less stable as a tandem setup
- There’s no unified structure holding both babies, so positioning takes more adjustment
- They slide around more during feeding
I found two Boppies worked okay for bottle feeding (propping bottles is a whole separate ethical conversation, but when you’re a solo parent of two preemies at 2am, you do what you do) but was less ideal for nursing because the babies weren’t at a consistent height relative to each other.
Head-to-Head: Twin Z Pillow vs. Two Boppies
| Twin Z Pillow | Two Boppies | |
|---|---|---|
| Price | ~$180–200 | ~$100 (two) |
| Purpose-built for twins | Yes | No (adapted) |
| Tandem nursing support | Excellent | Okay |
| Tandem bottle feeding | Excellent | Good |
| Tummy time | Yes | Yes (individually) |
| Portability | Low | Higher |
| Versatility after twins phase | Limited | High |
| Stability during feeding | High | Moderate |
| Cover washability | Yes, zippered | Yes, removable |
What About the Twin Z vs. the My Brest Friend Twins?
The My Brest Friend Twins pillow is the other main competitor. It straps around your body (vs. the Twin Z which rests on your lap) and gives you more freedom of movement. Some people prefer it; I found the Twin Z more comfortable for longer sessions and found the strap on the My Brest Friend uncomfortable over time.
The My Brest Friend Twins runs around $80–100 and is worth trying if you find the Twin Z too large or unwieldy.
Preemie-Specific Consideration: What I’d Tell NICU Parents
If your twins came early and spent time in the NICU, you may find the Twin Z slightly large for very small babies at first. We used rolled blankets and positioning aids to adjust the fit in the early weeks. By 8–10 weeks corrected age, it worked perfectly.
The NICU staff introduced us to the importance of positioning for preemies specifically — head support, hip alignment, airway positioning. The Twin Z supports all of this well once babies are big enough to fit it.

My Actual Recommendation
Buy the Twin Z. If you’re having twins and plan to breastfeed or tandem feed at all, it pays for itself in saved time and sanity within the first month. The $180 is not a discretionary purchase when you’re solo parenting two babies on two hours of sleep.
Keep or buy one Boppy as well for solo feeding sessions, side-lying nursing positions, and later use.
The total investment for both is around $230–$250, which sounds like a lot until you account for the fact that you’re keeping two humans alive simultaneously.
