When babies start to stand, do they stand on their tip toes at all?

Yes, some children do stand and walk on their toes. It's nothing to be overly concerned about unless your child is over 2 years of age and exhibits other symptoms such as abnormally developing fine motor skills and bad coordination. http://www.babycenter.com/0_your-child-is-walking-on-her-toes_12580.bc
