Learning to stand and walk - 9-11 months old

Don't exactly know when you start to learn to stand on your feet without holding and walk with support. Before mummy realise that you could balance yourself, you already started walking 1 to 2 steps. Mummy still remembered that because Grandma was babysitting you at that time, ya, you started walking on your own around the 3rd week of July. Wow, after that, mummy will have to chase you when changing diapers for you!
