Two of my children used a baby walker, and my third baby did not. He learnt to walk much faster than the other two. I dont beleive there is any proof these aid walking and in fact can cause back ache if the baby is left in them to long and they are not good on young legs and feet as they have soft bones still trying to form at this age. Just remember A baby cant tell you he has any aches or pains from sitting too long, or if his legs are in a bent position.
