10 things your kids need for back to school

1. Backpack
An overloaded backpack can cause back or neck strain, or worse, so look for lightweight models and encourage kids to pack light. Two straps are better than one, so avoid single-shoulder sling models, which put all the weight on one shoulder rather than dispersing it across two. Look for well-padded straps that won't dig into your child's shoulders, and consider whether a wheeled model (which have been gaining in popularity) will fit into her locker (when in doubt, phone your school office and ask).  Material-wise, rip-stop nylon blends will last longer than trendy clear vinyl materials.

2. Combination lock
Look for a strong and sturdy combination lock, not tiny novelty locks like those sold for diaries and coin boxes. Have your child write down their combination and keep it in their bedroom and give you a copy for safe keeping as well.

3. Lunch kit for litterless lunch
Bento box, tiffin pail, lunch kit or whatever you want to call it, your kids should have a reusable lunch set to ensure healthy, litter-free meals. Packed-from-scratch lunches are almost always healthier than fast food or litter-producing convenience packages. Look for separated compartments and secure, leak-proof lids so you won't have to rely on additional plastic wrap or foil.

4. Reusable water bottle
Save money and the environment by using a water bottle, not bottled water. Stainless steel, coated aluminum or BPA-free "safe" plastic bottles will keep your kid hydrated without risk of any leached hormone-disrupting chemicals. TIP: Have younger kids put on and take off the lid before buying – some are harder for little hands to maneuver.

5. Wrist watch
Get them a wrist watch so there's no excuse for tardiness. Whether you go with a digital or old-fashioned analog clock format, is up to you and your kid, but a shock-proof, water-resistant model is best.
