One of my 5yo twin sons is going through a phase where he likes to run away when out of the house. It took 30mins to find him inside BigW on one occasion. Several times we have been very close to dialling 000 but found him.
I have seen a range of different trackers on the net. The bluetooth ones seem extremely limited in terms of range, the GPS ones require a sim card with data to operate. I have been thinking an old mobile with gps enabled and a tracking app.
We have considered, reins, tying to brother/parent/streetlight, bungy cord, shock bracelets, helium balloons etc, so please don't suggest these.
Does anyone have any recommendations how best to go about keeping him safe but giving him some freedom to roam?
Use your eyes and hands. Be a parent.
5 year olds shouldn't have 'freedom' in shopping centres or public places.
At that age, your job is to supervise.
