Once a baby starts crawling, they spend a lot of time on their hands, knees and elbows, so what covers those spots matters more than before. Full-length sleeves and pants, rather than short-sleeved rompers, give some cushioning against hardwood, tile or outdoor surfaces, and flat seams mean there's nothing scratchy rubbing against skin that's now in near-constant contact with the floor. Epic's muslin pieces are double-layer and pre-washed, so they arrive already soft rather than stiff out of the packet, and how muslin baby clothes should fit is worth checking before buying a new crawling wardrobe: too loose and a hem turns into a trip hazard, too tight and it restricts the exact movement a new crawler is practicing.
Crawling is also a workout. A baby who's pulling themselves across a room generates more body heat than one lying still, so the loose, open weave of muslin cotton earns its place here: the gaps in the weave let air move instead of trapping heat against the skin. That's especially true indoors, where a fan is often the only cooling on hand, and what to dress a baby in when a room only has a fan covers how to judge coverage when there's no air conditioning. The fabric will crease fast once a crawler starts dragging themselves over it, and that's normal, not a sign of poor quality.
Crawling clothes get dirty fast: knees and palms pick up everything from food to dust, so expect to wash more often than before. Epic's pieces hold up to a cold, gentle machine wash, tumble dried low or hung to dry, no fabric softener or high heat needed, and the cotton actually softens more with every wash. Sizes run roughly newborn to 4 years, so there's room to size up as a crawler turns into a cruiser, and because Vanessa and Bob source and design these pieces in Bali, Epic ships worldwide with tracked delivery and takes unworn returns within 30 days if a size or style doesn't work out.
