Hi mums! Quick question for all of you. Have you experienced any challenges when your child reaches the age of 3 to 4? I've been feeling so exhausted lately with the endless chatter and unlimited energy of my 4-year-old DD. On top of that, she's getting more and more defiant and would often challenge my patience. It feels like the more words she learns and the more she learns to do things on her own, the more defiant she gets. What suggestions do you have to tone down her defiant attitude while teaching her to be independent?
