Does your 4yo have older siblings? They do tend to lead the younger ones astray. Firstborns learn all the tricks at school, bring them home and practice on their younger sibs. Fairly good odds Charlotte or George indulge in this sort of behaviour! Whatever, he’s a 4yo up late, in extraordinary environs, lots of strangers, hyper stimulation, full-on weekend. It was brave taking him out, tbh 😬
