👩👧 Personal Tips from a Mom Who’s Done It
- Plan Around Nap Times – The sweet spot is late morning or mid-afternoon.
- Don’t Overplan Activities – One or two stations are enough. They’re ONE!
- Take a Family Photo Early – Before cake, chaos, and naps!
- Prep a Diaper & Cleanup Station – For quick outfit swaps or wipe-downs.
- Hire a Photographer (or assign someone) – You’ll be busy. Let someone else capture the joy.
💡 Final Thoughts
Your baby’s first birthday isn’t about impressing anyone. It’s about celebrating the miracle of their first year and honoring your parenting journey. Whether it’s a backyard bash, a themed picnic, or a simple cake at home — it matters because it’s filled with love.
Choose the ideas that work for your space, budget, and baby’s personality. Don’t stress over perfection. Just show up, laugh a little, cry a little (you will!), and take in every second.
Because believe me — the first year flies by, but the memories last forever. 💛
