- Ensure your baby always has clean, comfy outfits
- Prepare for seasonal shifts (like layering in fall or bundling up in winter)

Bonus Tips for Baby Clothing Planning
1. Don’t Buy Too Far Ahead
Babies don’t follow clothing labels perfectly. Some 3-month-olds fit into 6–9M clothes, others don’t.
2. Consider Laundry Habits
If you do laundry daily, you can get away with fewer items. If you wash every 3–4 days, stock up.
3. Season Matters
Buy based on the age your baby will be in a given season—not the current one.
4. Avoid Over-Registering
Only add the clothing basics to your registry. See what you get at your baby shower first.
