frange(), a range function with float increments (Python recipe) by Dinu Gherman ActiveState Code (http://code.activestate.com/recipes/66472/) Sadly missing in the Python standard library, this function allows to use ranges, just as the built-in function range(), but with float arguments. All thoretic restrictions apply, but in practice this is more useful than in theory.
When I worked at a daycare we would have bike day during the summer when kids, aged 3-5, could bring in their bikes and ride them, most of the kids were on big bikes with training wheels and a few of the 4-5 year olds were without training wheels.
A bike carrier is a no-no for such a young child. Your child needs to be at least 1 year old before considering this. He should always were a helmet and he will not have the strenghth to do so until he is a year. Ask your ped if you don't believe me. was wondering if any of you moms have used any attachments or carriers on your bike for your infant (5 - 6 months old). He can't sit up by himself yet but can sit well when leaning on something.
