What you need

• About 77 diapers, so one pack of 100 in size 1 or size 2 covers it with spares.
• About 90 rubber bands (thin, small ones): one for each roll and a few for the rings.
• A cake board or sturdy plate, about 14 inches wide.
• 3 cylinders for the centers: about 3.5 inches wide for the bottom (a tall can or a big bottle), 2.5 inches for the middle, and 2 inches for the top (small water bottles). Each should be about 5 to 6 inches tall.
• Wide ribbon, about 4 yards, in one or two colors.
• Tape and double-sided tape.
• A topper, such as a small plush toy with no small parts.

Counts are planning numbers. The exact number depends on the diaper brand and size, so buy a few extra and adjust.

One pack of diapers and a few simple supplies are enough.

Step 1: Pick diaper sizes

A newborn grows out of the smallest size in a few weeks, so size 1 and size 2 are the more useful gift. Use one size for the whole cake, so every roll looks the same. Avoid very small sizes unless the parents asked for them. Check the pack for the weight range.

Step 2: Roll the diapers

Lay a diaper flat, fold it in half, and roll it tight from one end to the other. Put a rubber band around the middle. Make about 77 of these, and each roll should come out about 1.5 inches wide and 5 inches tall. A neat cake needs even rolls.

Even rolls make an even cake.

Step 3: Build the bottom tier

Stand the large cylinder in the middle of the cake board and tape it down. Stand rolled diapers around it in rings, upright and snug against each other. A ring holds about the circumference divided by 1.5 inches. For a 3.5 inch cylinder, the first ring is about 10 rolls, the next about 16, and the third about 22, which is about 48 rolls and a tier about 12 inches wide. Put 2 or 3 rubber bands around the outside ring to hold the tier tight. Keep the top edges even.

Step 4: Build the middle and top tiers

Set the middle cylinder on top of the bottom tier, in the center, and secure it with a strip of double-sided tape under it. Ring it with 2 rings, about 8 and 14 rolls, which is about 22 rolls and a tier about 8 inches wide. Put a rubber band around the outside. Set the small cylinder on top with tape and ring it with about 7 rolls, a tier about 5 inches wide. Each tier is smaller than the one below, and each should be stable before you add the next. If a tier leans, remove one roll and press the ring tighter, or add one roll to fill a gap.

The three tiers are built before the ribbon goes on.

Step 5: Add ribbon

Wrap the ribbon around each tier to cover the rubber bands. The three tiers need about 2.5 yards, and the bows take the rest of the 4 yards. Use a small piece of double-sided tape at the start and end of each wrap, and tie a bow or tape the end flat. Try a wide ribbon on the bottom tier and a thinner one on the top. Keep the tape off the diapers, so the parents can use them clean.

Step 6: Add the topper

Place a small plush toy on the top tier. Check that the toy has no small parts, loose buttons, or loose ribbon. Another idea is a paper flag with the baby’s name written by hand. Tuck a small card in the ribbon so the guests know who it is from.

A ribbon on each tier and a plush topper finish the cake.

What it costs

These are planning estimates for U.S. stores. The bottles are free if you reuse ones from home. Prices vary by store and region. See our budget baby shower decorations for more low-cost ideas.

A mini version

For a smaller gift, make a one-tier cake: tape a 2.5 inch bottle to an 8 inch plate, and ring it with 2 rings of about 8 and 14 rolls, which is 22 diapers. Add ribbon and a small topper. It costs about $20 and takes about 30 minutes.

Ribbon and color ideas

• Neutral: cream and sage green, which suits any baby.
• Boy: light blue and white. See our boy baby shower ideas.
• Girl: blush pink and cream. See our girl baby shower ideas.
• Gender neutral: soft yellow and gray. See our gender neutral baby shower ideas.
• Theme match: choose ribbon in the shower theme colors.

Safety and practical tips

• Keep it clean: wash your hands first, and keep the cake covered until the shower.
• Toppers: use a plush toy with no small parts, and no hard decorations.
• No glue on diapers: use tape on the ribbon only.
• Transport: carry the cake in a box or a laundry basket so it does not tip.
• After the shower: the parents can take the cake apart and use the diapers. Tell them to untie the rubber bands.
• Heat: keep it out of direct sun.

Mistakes to avoid

• Only newborn size. Babies outgrow it quickly.
• Loose rubber bands. Use enough to hold the ring tight.
• Uneven rolls. The cake leans.
• A toy with small parts. Check the topper.
• Making it too early. Make it 1 to 2 days before.
