Frequently Asked Questions
Are these costume-pajamas safe for sleep?
Yes, they’re designed as soft onesies suitable for sleep, but always follow normal safe-sleep rules: place baby on their back, avoid loose accessories, and choose the right size so the sleeper isn’t too loose around the face.
How should I size these if my baby is between sizes?
Sizing can run roomy for some DarkCom listings; if your child is between sizes and you want a snugger sleep fit, consider sizing down. If you want room to layer under the romper for colder nights, size up. Always check the seller’s measurement chart first.
Will the fabric stay soft after washing?
Customers consistently report that the flannel remains soft after multiple washes when cared for per instructions (gentle cycle, low-heat drying or air dry). Avoid high-heat drying to extend the fabric’s life.
