Tip for Parents:
Prioritize Comfort Over Complexity
Babies’ first costumes should feel like clothing, not a costume obstacle course. Soft, breathable fabrics like cotton or fleece are gentle on sensitive skin and help prevent overheating or irritation. Avoid scratchy materials, tight elastic, or heavy layers that could make your little one fussy
Choose Easy On & Easy Off Designs
Halloween often involves diaper changes, feeding, and moving between different environments. Costumes with snaps, zippers, or velcro make quick changes a breeze — especially when you’re juggling a fussy baby, a stroller, and a camera.
Skip Masks & Unsafe Headgear
Tiny masks, rigid helmets, and tight headgear can obstruct breathing and vision. They can also cause irritation or leave your baby uncomfortable during photos or outings. Instead, choose a themed hat, hood, or headband that complements the costume without restricting movement.
Avoid Small Parts & Choking Hazards
Babies explore with their mouths, so avoid costumes with loose beads, buttons, sequins, or removable decorations that could detach and pose a risk. Securely attached details are your safest bet.
Think About Temperature & Layers
Fall weather can vary widely — chilly evenings one minute, warm afternoons the next. Plan your costume with comfort in mind: layering allows you to add or remove warmth easily. For cooler nights, try a thermal onesie or cozy layers under (not over) the costume.
Safety First: Flame Resistance & Visibility
Traditional Halloween decorations often include candles or jack-o’-lanterns, so choosing flame-resistant costumes adds peace of mind. Look for flame-retardant fabric labels when possible. For evening trick-or-treating, adding reflective tape or a glow stick to outfits or stroller toys increases visibility in low light — making your baby easier for drivers and other families to see.
Plan for Photos, Then Play
Baby’s first Halloween lasts longer in photos than it does in real life! If they aren’t thrilled about wearing a full outfit for long, plan a quick photo session and follow it with a more comfortable outfit for the rest of the evening. This way, you capture the memories and keep your baby happy.
