Well, be strong and don't react much when kid gets angry or starts crying. Few things are just out of control, pampering them when they are angry or crying will allow them a way out to get choclates

Actually most children this age, go through this phase. The key is to not shout and make your child understand that this behavior is understandable. It is also possible that he picks up these habits from school.
Whenever your child misbehaves, take him to the side and explain to him that this behavior is unacceptable. Also, you can take away some playtime or TV time, this way your child will become more aware that such behavior is unacceptable. Children are unable to comprehend the consequences of their actions if you scream or speak in a stern voice. Also, there is no harm in correcting in public as well. Just set boundaries as you are the parent.

Don't get frustrated,as you can't change your family situation & nothing to be blamed upon you.If you show your anger at her,she'll feel in that way.
Be relaxed & patient, as your baby needs you & more importantly you are the only person present for her.
You can take homeopathic medicines to control your negative behaviours,( as I've used for my mental troubles ),if u want.
