Baby 15 months old and walking!

Baby is 15 months and he just started to walk unassisted! This is a milestone for baby. For the past couple months, he was just crawling all over the place with some minor walks by bracing himself on furnitures.
It took a lot of prompting to get him to try walking more. The motivation came when I took him to the shopping mall and decideed to just hold one hand and let him walk assisted.
He would look at others walking by and he would notice other children who would walk. Going home later, he would try to walk more assisted. And when he was ready, he walked without support! And in some instance still managed to walk unassisted while holding on to some bulky containers!
He still need more encouragement so will let him walk more while holding his hand.
He is still a little wobbly and I noticed his walk was rather bow legged. A quick check online from baby centre, and it was explained that it was normal. Baby will grow out of it when his muscle strengthens. So now just need to encourage him to walk more!
