THE PARTY BAG FILLER BUYING GUIDE
Here’s a quick buying guide to help you make great choices when buying party bag fillers or favours for your three-year-old birthday party.
1. Age-Appropriate: The first and most crucial consideration should be whether the items are suitable for the age group. For 3-year-olds, ensure that there are no small pieces that could pose a choking hazard.
2. Safety Standards: Look for toys or items that meet safety standards. These should be free from toxic materials and should have smooth edges to prevent any harm.
3. Eco-Friendly: Consider choosing environmentally-friendly party bag filler options. This not only helps preserve the environment but also generally ensures products are free of harmful chemicals. I’ve got a whole post on eco-friendly party bag fillers.
4. Educational Value: If possible, choose items that offer some educational value, such as simple puzzles, books, or craft supplies that promote creativity and learning.
5. Fun Factor: Make sure the items you select will be fun for the kids. Think about what children of this age group typically enjoy. Things like stickers, colourful items, or character-based items can be big hits.
6. Durability: Consider how long the item will last. It’s better to give one or two high-quality items that will last a while than many that will break easily.
7. Practicality: Practical gifts can also be appreciated, especially by parents. Things like sippy cups, toothbrushes, or reusable snack bags can be great choices.
8. Allergy Considerations: If you’re giving food or cosmetic items, ensure they are allergy-friendly to cater to all guests. Avoid common allergens like nuts or gluten in snacks.
9. Cost-Effective: Parties can be expensive, so look for cost-effective items. Buying in bulk can often save money.
10. Ease of Wrapping/Packing: Finally, consider how easy it is to pack the items into a party bag. Too large, too small, or awkwardly shaped items may not work well.
Remember, the aim is to provide a small thank-you to the children attending the party, and the gifts don’t have to be extravagant. The most important thing is that the children have fun.
