My honey can fit into a 4t shirt. His 2t is starting to fit a little small. I am sad he is growing up to fast. Also my oldest love bug has out grown his new shoes that I got him last month so now I get to go shopping again for both of them. Why must kids grow so fast I can't keep up with them it's like they every month.
