ZoE almost always has her topknot in at night. Although, if it's starting to look a lil rough and will need to be redone, I'll take it out and let her sleep without it and put a new one in first thing in the morning.
ZoE will be 25 weeks old this Thursday, so I'm she's still in topknot training
She's doing great and doesn't mess with her bows at all or try to get them out.
