my baby is now 11 month half but she haven't start to walk alone......what to do.....

A. not a problem.wait till 1. 5 years of age to walk. milestone delay is when baby does nt achieve expected motor /language milestones as per age. -neck control starts by 2 mnths and develops full neck n head control by 4 to 5 mnths - sits with support 6 mnths, without support 8 mnths - stands by 1 yr and walks by 1.5 yrs. If baby does nt have all these by this age , you need to see a doctor
