You've been given some great tips, some I'll even try myself! Moo has hated having his nappy changed for months. He crosses his ankles, raises them up and then BAM! Whacks me on my wrists or hands! He'll also twist his body completely around if I hold onto his feet (to stop the previous issue) so he's practically dangling!
He screams and cries as if he's being totured, completely does my head in. I hope we both find a solution!
