Question mainly relates to school jumper/polo shirt sort of stuff.
DS's outgrown uniform has his name neatly sewn into all items (PFB).
DD is going to wear some of it. Do you cut the labels showing the eldest's name out and put the younger one's name in it? I have been thinking of crossing out DS's first name in laundry pen and putting DD's name in pen, leaving the sewn label showing the surname. What do people do?
