I know children having phones can be problematic, but my granddaughter just had her first video call with my sister's granddaughter yesterday and me, my sister, & my son were just overwhelmed by the adorableness, plus the opportunity for them to make friends. (These cousins are only a year apart but live in different states & had only met once--about 2 years ago on my phone)
Plus, just to brag, my granddaughter knew enough NOT to answer a strange number until Dad told her it was okay. 😍
