A packing list tells you the goggles are in the bag. It does not tell you whether they still seal, whether the cap is a size too small, or whether the warmth suit your baby wore in spring still reaches the wrists. This sheet is the other half: one test per item, what a pass looks like, and the signal that says replace it. Run it on the kitchen table before lessons start.

Four checks, in order. Stop at the first failure and try a different pair — a strap cannot fix a gasket that does not match the face
| The check | What a pass looks like | What a fail tells you | Pair A | Pair B |
|---|---|---|---|---|
| The suction test | Press the goggles gently against the eyes with the strap off. They hold with a light vacuum seal for a few seconds | If they drop straight off, the gasket does not match your child’s eye socket shape. No strap tension will make that pair seal in the water | ______ | ______ |
| The nose bridge | The bridge holds both eyecups flat against the face. Many kids’ goggles ship with interchangeable bridges — try the other sizes | Too narrow pulls the cups outward at the sides; too wide breaks the seal in the center. More goggle failures are bridge mismatches than size mismatches | ______ | ______ |
| The strap | Snug, sitting across the back of the head at roughly ear height. A split strap holds better for diving and underwater swimming | If it only seals when cranked tight, the pair is wrong. Over-tightening distorts the gasket and actually breaks the seal | ______ | ______ |
| The 20-minute mark | No deep red rings after 20–30 minutes of wear, and no immediate fogging on entering the water | Deep marks or headaches mean too small or too tight. Persistent fog from the first minute usually means the anti-fog coating is spent | ______ | ______ |
A child with thick or long hair may need an adult-size cap at eight years old. Fit the hair, not the birthday
| What you see | What it means | What to do | Ours |
|---|---|---|---|
| Red marks on the forehead, pops off mid-swim, or will not cover all the hair | Too small | Move up a size. Check the manufacturer’s head-circumference measurement in centimeters rather than the age label | ______ |
| Air pockets, slides off easily, hair escapes at the edges | Too large | Move down a size or try a different brand — cap shape varies more between makers than size labels suggest | ______ |
| Snug without pain, covers all the hair, stays on through turns and dives, leaves no marks when removed | Correct | Note the size and the head measurement so the next one can be bought without a trip to the shop | ______ |
| Child refuses to wear it at all | Usually a material or choice problem, not a size problem | Silicone suits most children; Lycra is gentler on sensitive scalps and thick hair; latex only if a program requires it. Let them pick the design | ______ |
Answer the temperature question first. Most families who buy a wetsuit for an indoor infant class did not need one
| Ask the program | The answer that decides it | Ours |
|---|---|---|
| “What temperature do you hold the water at for infant classes?” | At 88°F or above with lessons of 30 minutes or less, thermal wear is typically not necessary. Consistently below 87°F, it becomes appropriate | ______ |
| “Is the pool indoor, outdoor, or open water?” | Outdoor pools vary seasonally and open-water programs vary daily — both push toward thermal wear regardless of the headline number | ______ |
| “How long is the in-water portion, really?” | Duration multiplies temperature. A 45-minute class at 87°F is a colder experience than a 20-minute one at 86°F | ______ |
| Has your own child shown a pattern of cold sensitivity? | Lethargy, blue lips or fussing within about 15 minutes in a standard heated pool is your answer, whatever the thermometer says | ______ |
If you do need one — the shoulder pinch test.
| Item | When it earns its place | How to get it right | Ours |
|---|---|---|---|
| Ear plugs | Ear tubes, recurrent ear infections, or a doctor’s recommendation. Otherwise optional | Swim-specific soft silicone or moldable plugs — not foam plugs made for noise. For children with tubes, some families get custom-molded plugs from an audiologist. Plugs reduce moisture, they do not eliminate it: still tilt the head to drain and dry the outer ear afterwards | ______ |
| Nose clip | Settling a nervous child, or backstroke | Comfort aid, not a fixture. Keep teaching nose-breathing and bubble-blowing alongside it so the clip does not become the only way your child can put their face in | ______ |
| Prescription goggles | A child whose vision correction genuinely changes how they experience the water | Run exactly the same four-step suction test. Corrective lenses do not exempt a pair from having to seal | ______ |
The one piece of gear on this sheet where the choice does affect safety — because it decides how fast someone can find your child in the water
Gear rarely announces that it has failed. These are the signs that it already has
| Item | Replace when | Checked on |
|---|---|---|
| Goggles | The gasket feels stiff or shows fine cracks, or the pair fails the suction test it used to pass. UV exposure hardens silicone, so a pair used for a full season can need replacing while still looking fine — retest the seal at the start of every season | ______ |
| Swim cap | It tears at the edge, no longer covers all the hair, or leaves marks it never used to leave | ______ |
| Thermal wear | The cuffs stop reaching the wrists and ankles, the neck gaps, or your child has moved out of the weight range on the chart | ______ |
| Ear plugs | They stop sealing, harden, or a molded pair no longer matches a growing ear canal | ______ |
| Swimsuit | The color has faded toward dark or muddy, the fabric has gone thin or transparent, or it no longer stays put when your child pushes off a wall | ______ |
| Life jacket (not optional gear) | Any tear, missing strap or broken buckle — and any time your child moves out of the weight range printed on the label. Check it against the label, not against how it looks | ______ |

Ten minutes with this sheet saves a term of leaking goggles — but the lessons are the thing that protects your child. Participation in formal swim lessons is associated with a large reduction in drowning risk for young children, and drowning remains a leading cause of death for children ages 1–4.
