My son is 9 months old turning 10 months.. He can stand on his own just so long as he's holding on to something for support. But he can't walk yet and stand without support. At what age could this start?

It's important to remember that all children's bodies develop differently. Some kids can walk and talk earlier than most, while others fall behind. That doesn't necessarily mean that there's something wrong with them. But if you do suspect that somethings is awry, it's always a good idea to talk to a medical professional.
