The best baby mittens that don't fall off

Why most baby mittens fall off

Baby hands are small, narrow at the wrist, and round at the back. Adult mittens get pulled on by a thumb gripping the cuff. Babies do not grip. They flap. So any mitten with an open elastic cuff slides right back off the moment the arm waves.

The fix is one of three design choices. A long stretchy cuff that goes up over the coat sleeve. A closure that locks the mitten on at the wrist. Or a mitten attached to the sleeve itself, the way old-school sleep gowns work.

If your baby is under six months, an attached mitten is almost always the better choice. Past six months, locking-cuff styles become more important because babies start pulling everything off.

What to look for, by age

The right mitten changes a lot in the first year.

• 0 to 3 months: Use sleeve-attached "no scratch" mittens, or buy onesies with fold-down cuffs. Babies this age cannot grip and should never have anything tied around the wrist.
• 3 to 6 months: Long stretchy cotton mittens with a cuff above the wrist. Bonus if there is a velcro tab for adjustment.
• 6 to 12 months: Lined waterproof mittens with a long gauntlet cuff that goes over the coat sleeve. A clip or velcro is essential at this age.
• 12 to 24 months: Wool or fleece mittens with a thumb. Toddlers want to point and grab. A mittened fist is fine for sledding, not for picking up snowballs.

The five mittens that actually worked

I tested fourteen pairs across one winter in a cold-enough city. Here are the five we kept reaching for.

1. Stonz Mitts (6 months to 4 years)

The closest thing to a perfect baby mitten. A long fleece-lined gauntlet that pulls all the way up past the coat sleeve, plus an adjustable toggle at the top. Waterproof shell. They stay on through sledding, snowball-making, and the world's most determined mitten-removal toddler.

Sizes start at 6 months. For under-six-month wear, the gauntlet is too long.

2. Zutano Cozie Booties / Mittens (0 to 12 months)

Soft fleece with a wide stretchy cuff that reaches well past the wrist. Best for indoor stroller use, walks where it's chilly but not full winter, or as a liner under waterproof outer mittens.

They do not survive wet snow. They do survive cold restaurants, grocery store freezers, and 40 degree walks.

3. Burton Grommit Mittens (toddlers, 2T to 4T)

For the toddler who insists on being a real little human. Burton's smallest size has a real waterproof shell, removable liner, and a wrist closure that velcro-locks tight. The price stings, but they survive everything.

4. Mittclips by Mommy's Helper

Not a mitten. A pair of clips that attach any mittens to the coat sleeves so they hang there instead of getting lost. We bought a four-pack and clipped them onto every coat. The mittens still come off, they just no longer disappear into the parking lot.

Worth more than half the mittens we owned.

5. Carter's "No Scratch" Newborn Mittens

The newborn classic. Thin cotton, sleeve-style cuff, comes in 4 packs. Use these the first few months so baby does not scratch their face, then donate them.

The pro tip: pull them up over the coat sleeve, not under. The cuff grips the sleeve fabric and stays put.

What to skip

• Mittens with a string drawcord. Strangulation risk. The AAP and the Consumer Product Safety Commission have both flagged drawstrings as a hazard on children's clothing.
• Mittens with a thumb on babies under 12 months. Babies cannot use the thumb hole. It just gives them a place to flop the empty thumb pocket and pull the mitten halfway off.
• Knit mittens with no liner. They look adorable, they let in snow within minutes. Fine for a photo, not for a walk.
• Mittens that match the coat brand. Most coat-brand mittens are an afterthought. The specialty mitten brands above win every time.

How to keep mittens on a baby who pulls them off

Some babies treat mitten-pulling as a personal hobby. A few tactics:

• Put the mittens on before the coat goes on, then thread the coat sleeves over them. The coat now traps the cuff.
• Use a one-piece snowsuit with built-in fold-over mitt cuffs for ages 6 to 18 months. Less mitten management, more nap time.
• Use mitten clips on everyone, even toddlers. The clips do not stop removal, but they prevent the loss.
• Bring spares. Always two extra pairs of mittens in the diaper bag in winter.

Washing and care

Cotton and fleece mittens go in the washer on cold, hang to dry. Wool mittens get hand-washed with a wool wash and laid flat. Waterproof shell mittens get a wipe-down and re-treated once a season with a fluorine-free DWR spray.

If you find that your mittens have started letting water through after a few months, that is the durable water-repellent finish wearing off, not a defect. A 10-minute reproofing brings them back.

The bottom line

Mittens that stay on a baby are a real thing, but you have to buy them on purpose. Skip the coat-brand mittens. Spend the $25 to $40 on a Stonz or Burton pair. Clip them to the coat. Bring spares. Your hands, your baby's hands, and your sanity will all be better for it.
