Quick Answer

Babies often fight the Zipadee-Zip because they're not used to the new sensation, the fit is off, or they're overtired when you put it on. Start by checking the size and fabric, then try introducing it during awake time before bedtime. If resistance continues, the EverSoft™ Bamboo version's lighter feel may help sensitive babies adjust.

Check the Size and Fit First

A Zipadee-Zip that's too snug can restrict movement more than a swaddle, while one that's too loose may feel unfamiliar and bulky. Measure your baby's weight and height against the size chart for the specific product you own—each size covers a range, and sizing up or down can make a big difference. The Classic Zipadee-Zip and the EverSoft™ Bamboo version share the same starfish design but the bamboo fabric has more give, which some babies prefer.

Introduce It During Playtime

Putting the Zipadee-Zip on for the first time right before bed can startle a baby who isn't expecting it. Instead, let your little one wear it for 10–15 minutes during a calm play session earlier in the day. This helps them associate the sensation with comfort rather than sleep pressure. Once they seem neutral or happy in it, move to naptime use.

Watch the Timing of the Transition

If you're moving from a traditional swaddle, your baby may still have a strong startle reflex that the Zipadee-Zip's starfish design doesn't fully suppress. That's normal—the design allows safe movement once baby starts to roll. If the startle reflex is the main issue, try using the Zipadee-Zip for just one arm at first, then both after a few nights. The Going Places and Lions patterns offer the same internal design, so choose whichever print your baby finds most soothing.

Diagnosis: Why Your Baby Fights the Zipadee-Zip

  • Symptom: Baby cries or arches back when you put it on: Likely cause: The fit is wrong or the fabric feels unfamiliar. Check size and try the EverSoft™ Bamboo version for a softer feel. If sizing is correct and baby still cries after 3–4 tries, consider the bamboo option.
  • Symptom: Baby wakes up upset after sleeping in it: Likely cause: Startle reflex still active or the room is too warm. The Zipadee-Zip is designed for safe rolling but doesn't suppress startle as fully as a swaddle. Try one-arm transition or use a lighter fabric. If your baby is already rolling, do not go back to a swaddle.
  • Symptom: Baby kicks and squirms but won't settle: Likely cause: Overtired when you put it on. Introduce the Zipadee-Zip during awake time first so it becomes a familiar comfort item. If after a week of daytime practice your baby still won't settle, the Zipadee-Zip may not be the right sleep sack for your child at this stage.
