An ounce of prevention is worth a pound of cure. Being prepared will always be more beneficial than cleaning up afterwards.
Same philosophy with life, will work the same for your baby. Check your diaper bags if they have the things in our list, to minimize the headaches of potential booboos while outdoors.
Firstly, diapers. Can't be called a diaper bag without a diaper. The amount depends on how long you think you might spend outdoors, and bring an extra just in case.
Second, baby wipes. Always double check the remaining amount before leaving. Then achanging pad. Disaster strikes when you least expect it, and you might have make do with any flat surface, so having a changing pad will greatly bring comfort to your baby.
Next are milk, water and/or baby food. Though if you are still breastfeeding your baby just having water bottle might be enough.
And also bring a change of clothes, again depending on the time you think you will spend outside.
Having all your baby's essentials in one place makes it much easier to manage everything.
