Martin pushs his train to walk more often. He's also willing to hold mummy's hands to walk around 30 feet each time. Sometime he'll free his hands stand alone. Although it's a bit late to start walking, Martin has made a good progress today. Mummy is happy to see that. Martin, you still have 3 more months to practice, take your time. If at that time you still not start to walk alone, mummy really have to concern about it.
