My little boys had one since 2. We've started using it for potty time! Letting him play little games as he won't sit on the potty and this has helped. We also take it out for when we are going for a meal but it gets taking off him when food comes out. We've downloaded a bunch of learning games on his and he gets to watch some of his wee programmes
We use it to entertain him whilst we're out. We've never had babysitters so he comes wherever we do! Plus very useful for the many hospitals appointments
We use ours for car journeys mainly and sometimes if we’re in a restaurant:)
Only use ours for long car journeys.
My 3 year old uses her brothers but we don't take them out of the house (unless on holiday) and we don't have them at meal times
