Toddlers love to imitate grown-ups¹, so old cell phones and toy versions are often big hits with little ones. But how soon should you give your child a real cell phone? An American Academy of Pediatrics expert says 11-12 years is the earliest. Kids who are busy talking, texting and playing games or music on their cell phones may spend less time interacting with other kids and family. Research says they also pay less attention to traffic and physical surroundings that could put them in danger.²

As hard as it may be, giving your toddler more independence could be a boon for both of you. She'll learn faster, gain self-confidence and be more comfortable on her own. Here are some techniques: Let her make her own decisions (within limits, of course), such as what to wear. Find chores she can help with, like folding towels or putting away the silverware. Whenever possible, let her do things her way, even if it takes longer. Ease separation anxiety by reassuring her you'll be back and gradually increasing the time you're away.
