My almost 3 year olds defiance lately has been unbelievable. He tells me No! He spits out his food unwilling to try something new , acting out , wining about anything and everything . I can not deal with it .

What the heck is going on!

I thought I was going thru terrible twos , looks like terrible 3’s is going to be even more challenging , especially with a newborn .

Help!!!!!??

Any advise to save my insanity welcomed !!!???!!!
