Our dds 5 and 7 (but 6 and 8 in January) would both love smart watches for Christmas. They're both very sold on the Vtech Kidizoom watch but I'm worried it's too young for the nearly 8 year old and she'd get bored of it quickly? I know the 5 year old would love it though. Does anyone have one with a kid this age? Or any suggestions for a kids smart watch for this age range? Thanks!
