The diaper advisor
Four questions → the right size, 2 brand picks and the cheapest way to buy.
Step 1 of 4
Diaper size by weight — quick table
Manufacturers grade diaper sizes by weight, not by age. The advisor uses the same logic as a starting point and adds fit, brand and buying-path recommendations.
| Size | Weight | Typical age |
|---|---|---|
| Newborn (0/1) | 2–5 kg | 0–1 month |
| Size 2 | 3–6 kg | 1–4 months |
| Size 3 | 5–9 kg | 3–9 months |
| Size 4 | 9–14 kg | 6–18 months |
| Size 5 | 11–16 kg | 12–24 months |
| Size 6 | 15–28 kg | 18–36 months |
| Size 7 | 17+ kg | from 30 months |
What the advisor also checks
- Brand fit patterns: Pampers runs smaller, babylove and Babydream more generous.
- Priority: price per piece, eco balance (Lillydoo, Naty), skin tolerance or convenience (subscription/Amazon).
- Buying path: drugstore promos (dm, Rossmann, Müller, Budni) are usually cheapest; online shops shine for subscriptions & eco.
- Active app coupons (dm coupons, Rossmann app, Payback) feed into the live deal cards below the recommendation.
