Sometimes, traveling alone can be fun but you can't leave your children behind, that's why most parents invest in
lightweight strollers or travel strollers. Travel strollers would help you keep your toddlers in check so that they wouldn't run off.
The best travel strollers are probably those umbrella strollers, called because they're as light and portable as umbrellas. Of course, because of the limited size, you can't expect pockets for baby bottles, diapers, etc.
Of course, there are also full featured lightweight strollers which features, canopy, rain cover, removable padding, and onboard storage. Of course the added portability would jack up the price to more than $100. There are also
tandem lightweight strollers availabe if you're traveling with two toddlers, the downside is that tandem strollers are bulky even if they are "lightweight" and you would probalby incur extra baggage charges.
The cheapest solution would be
baby carriers, particularly backpack baby carriers but make sure your husband is traveling with you because, well, carrying a baby on your back for long travels would take a toll on you.
Whatever kind of stroller or carrier you choose, traveling with toddlers doesn't have to be a headache.
