My son in 4 years old. Just recently(in the past 2 weeks) he has started having a lot of up and down emotions. He rarely has tantrums but the past 1-2 weeks has been several tantrums each day. He argues, throws things…I know he is testing limits. But is that it? Is this normal? All of a sudden? Should I be worried about something serious? Or is this just a phase that we need to tough it out? I’m worried and stressed.

Please some real advice.
