Of course he looks so much older now!
The weather seems to have turned toward spring here. M4 went out to play over the weekend and had a lot more fun. He still is not very good in the boots, but at least he was giving it a shot! I found a pair of M2's old shoes and we might have M4 play outside in those instead - they won't stay pretty for long, but he could be a little more sure-footed.
