Our daughter hates having her teeth brushed so we've started watching videos on our phones as a distraction. The alternative is pinning her down whilst she kicks and screams and its like torture for all of us. But there's so much anti-phone/screen stuff out there now I'm worried we're doing something wrong despite it seeming like the lesser of two evils. Its usually about 3-5 minutes of bluey, or genevieves playhouse. Shes started asking to watch stuff at other times and we say no despite the ensuing tantrum.
