walking babies ?

Nyjul • Snapchat- kiya.kiyaaa💜 I’m 17🦋 1 year old son ( peytonn ) daughter otw ( alyce ) 💕

When do babies start walking ? I have a 9 month old . He won’t try and walk by his self and every time I help he just drops to the floor , he can balance for 2-4 seconds

Just would like a little advice on how to help him ..
