Ok my friends boyfriend gave me his stroller cuz he is moving and he wont have his kid no more and the kids mom already has a stroller....Ok well its a saftey 1st stoller and its like blue (lol I dont think that really matters, but anyways).... Ok it has one of them mounting bars for a carseat, but I dont have a carseat yet, and I want to get one that will attatch to this stroller... Do I have to buy a certain kind of carseat? Does it have to be the same name brand? Do I have to buy a whole travel system to get the whole deal? Like does it have to be made specificaly for that stroller or does it not matter.... I dont know which carseat to get for this stroller, I was looking at walmart.Com and target.Com and I cant find a seperate carseat that I could buy for this stroller, can anyone help me? Like what am I supposed to look for? Like an attatchment type deal or what? Im so confused with this!
