My dear find that my son has not enough shirts, actually he has shirts but some maybe not so suitable to wear anymore. We still kept in the closet. So time to remove shirts that he can't wear any more.
He's getting bigger now, he's wearing adult under wear. I can't believe but he's wearing L size. He's 50kg now, so better watch his weight. He's growing taller and taller, so I think he's about my chin if he's standing next to me.
Children clothing no longer fits him.
