OP here — the wandering-off-mid-call struggle is so real with little ones. What works better for us than the 'big weekly call' is short, frequent, low-pressure moments: a two-minute video to say goodnight, reading them a bedtime story on screen. Little and often beats one long awkward call.
The hardest part of retiring abroad isn't the admin, it's missing the grandchildren growing up. Video calls with little ones are hit and miss — they wander off mid-sentence. For grandparents doing this at a distance, what genuinely keeps the bond strong across the miles, beyond the obligatory weekly call?
