Tying shoelaces, whistling, and using cutlery are the hardest things to teach young children – according to a poll of parents. Faced with tantrums, short attention spans, and spending so much time indoors, a study of 2,000 moms and dads has revealed the skills they’ve found trickiest to pass on. Learning to ride a bike is the fourth most challenging activity to teach, followed by how to tell the time and how to button a button. Helping their children learn to swim, to brush their teeth, to try different foods and to successfully write their name rounded off the top 10. The study also found 83% of parents take pride in helping their kids develop – despite the challenges. Other skills parents find tricky to teach include potty training, getting dressed, putting toys away and explaining the difference between left and right. Mastering the alphabet isn’t easy either – and neither is showing them how to count money.
