Some parents choose to put a phone number on a label, and others choose not to. It’s important to keep your kid’s safety in mind when labeling items. That means putting labels in less visible areas, such as inside tags, and using initials or codes such as hearts or stars to signify what items belong to your child. If you know your child is under constant supervision by adults they know at daycare or school, you might feel more comfortable putting your phone number on a label.
