Late walkers?? How old was your baby when they started FULL BLOWN, NO HELP walking?? Mine 1st was 9 months. My 2nd still Is not walking independently and she will be 17 months March 2nd. The dr says dont worry about it until she is 2. But me being a mom, I'm still worried. She walks holding on to stuff and stands up holding on to stuff for long periods of time. But when it comes to doing anything walking or standing Independently she simply can not do it. I bought her those white high top baby shoes to wear around the house but of course after a while she takes them off cause they dont stay tied for long. I know all babies are different but still. When did your kids start walking??
