I’ve mentioned keeping your stroller safe from thieves before. There’s another type of thief that you need to be aware of, but one with less malicious intent. Squirrels and birds will often check out unattended strollers, looking for a quick snack. Don’t leave food where they can find it! Popcorn especially seems to be a favorite treat, and it’s fairly easy for critters to get into popcorn buckets. If your food isn’t hidden away and secured, you could come back to a mess.
