Two months ago, when Justin boy was 15 months old, prefers crawling then walking. Walking was a great challenge for him. Yet he found walking very fascinating.
And now, 17 months old, he roams the house, walking. Putting on his red backpack is his favourite :-D
Time really flies. Justin boy is learning new things (and practice them) everyday. With the stress at work, coming home to play with him is a good remedy.
