If you're looking to buy a stroller, there are many things you should think about before you even begin your search, or you'll just get overwhelmed. You wouldn't think that there could be that many different strollers out there, or that many different types, but you'd be surprised!
First off, you need to think about what you'll be using the stroller for. If you're just going to be using it in the mall for example, a regular stroller will work fine. But if on the other hand you'll want to use the stroller while jogging down the street, or even on grass, you'll want to make sure that you get a jogging stroller that was made for that type of exercise. Otherwise you'll end up hating your stroller.
Another thing you need to think about is if you need a folding stroller or not. If you want to be able to tuck the stroller into a small space (such as your trunk), you may want to specifically find a stroller that will fold. If you don't care, then you can get a regular stroller that will be bigger, and will probably be more comfortable and have more space to hold things.
If you have twins, or have another child already (or plan on having another one), you might want to consider a double stroller. This way you can easily transport them both around, and won't need two strollers.
On top of all of that, you may want to think about how much space you want on the stroller. Some people like having storage space to put bags, or a drink, etc. On the other hand, if you want something as small as possible, you may not care about having any extra space.
Once you have all of that figured out, you can start looking into the fun stuff, like the color of the stroller. You wouldn't believe how many different color strollers there are out there. The same thing goes with brands of strollers. There are a ton of different stroller brands out there, and each of them have quite a few different choices.
Make sure you don't forget about your budget. There are strollers at all different prices, so no matter what your price range is, you'll be able to find a stroller in that price range. So don't think you have to spend a lot of money to get all of the features you're looking for. Just be patient, look for sales and at websites online, and you'll be set.
