Re: Car seats/strollers
One more suggestion.....please put some weight in the stroller before test driving it.......don't push it around empty.
And when you put weight in it, don't just put the baby's weight, put some extra in to accommodate for the diaper bag, groceries, shopping bags, a purse if you will carry one.....etc.
Once all this weight is in, then try pushing the stroller.......this will give you a more accurate representation of what it will be like.
