Children lie when they feel they actions will not be accepted by their parents. Assure your child that you will be there to support them when things go downhill.
Intolerance is not the same as possessiveness. It might have underlying reasons.
Children do not understand the concept of "stealing" so instead of dealing with this situation using your anger, it is better to sit with your child and make him/her understand why they should not be doing this.
All humans are stubborn, more or less. That does not mean you cannot teach your child to put their foot down and patiently listen to what the other person has to say.
Before assuming that your child is a disobedient child, assess what according to you is disobedience.
Children model their parents the most. Develop the listening skill yourself and then help the child to achieve the same.
It's normal for kids to get cranky but as a parent do not lose the cool.
If a child is not playing alone, it does not mean (s)he is an introvert child, there can be other reasons as well.
A child is entitled to his/her choices of choosing friends and playmates.
Back answering is not just a misbehaviour of your child. There might be underlying reasons for that.
Every child needs full attention of a parent. So, pause and reflect on your parenting to make sure none of your children feel left out.
Shouting only makes matters worse, be it you or your child.
Waking up early is always a task but rather than making it a happy start we tend to begin with tantrums.
A child is bound to throw a tantrum because who else if not the child. This does not mean the tantrums can not be tamed.
It becomes a little awkward to explain such things to your child.
