Tips for Mom & Baby Costumes

1. Comfort is Key: Baby needs freedom to crawl, sit, or walk. Avoid itchy or tight materials.
2. DIY vs Store-Bought: Mix both for affordability and creativity. Even small details like hats, capes, or props make a huge impact.
3. Safety First: Avoid small accessories or anything covering baby’s face. Keep props soft and light.
4. Plan Ahead: Popular costumes sell out fast—grab your favorites early.
5. Photogenic & Pinterest-Friendly: Use bright colors, matching patterns, and bold accessories for eye-catching photos.
