Size Guide
Choose Baby Paddle Pals sizes by your child’s current weight first—not age alone. Mermaid Dreams, Sea Adventure, and Ocean Pals are different products with different ranges, so use the chart for the exact item you are buying. Check the product label before use and supervise closely in and around water.
Use the vest chart for Mermaid Dreams or Sea Adventure. Use the swim diaper chart for Ocean Pals. Their size ranges are not interchangeable.
Swim vest size chart
| Product | Labeled range | Design | Shop |
|---|---|---|---|
| Mermaid Dreams | 6–24 months Up to 33 lb / 15 kg |
Front zip with an adjustable under-leg strap | View vest |
| Sea Adventure | 2–6 years 33–66 lb / 15–30 kg |
Open-side foam vest with cross-over back straps and an under-leg strap | View vest |
Do not use the two vest ranges interchangeably. If your child is outside a product’s labeled weight range, choose a different model. Age ranges are only general guidance because children of the same age can be different sizes.
Ocean Pals reusable swim diaper size chart
| Size | Weight | Waist | Thigh |
|---|---|---|---|
| 6–12 months | Up to 24 lb / 11 kg | 13.4–18.5 in / 34–47 cm | 6.7–10.2 in / 17–26 cm |
| 12–24 months | 24–33 lb / 11–15 kg | 16.5–19.7 in / 42–50 cm | 8.7–12.2 in / 22–31 cm |
Ocean Pals should sit close at the waist and legs with no open gaps. If your child is between sizes, compare both waist and thigh measurements. Do not size up simply for growing room.
Quick fit check before water time
- Confirm the label: use the exact weight range printed for your product.
- Fasten every strap: adjust the straps used by that vest model.
- Check vest rise: gently lift at both shoulders. The vest should remain on the torso and not rise over the ears or face.
- Check movement: your child should be able to raise their arms and bend comfortably without the vest shifting excessively.
- Check diaper openings: the waist and legs should remain snug during a squat and a few kicks.
