Raising kids is indeed difficult. I totally understand, my step-kids are now teenagers. The challenges you face in raising a child will help your kids and yourself grow. You will face challenges but it’s nothing you can’t overcome. It’s never easy but to see your child grow up into a great, happy and healthy human being is what matters. Keep them close now as teenage years will be the most toughest times. Sorry you’re frustrated. He is totally being a kid! Stay strong and enjoy them as toddlers =)
