The 3's are worse than the 2's. I can only assure you that the 4's are magical. Being pregnant (around the same as you) my hormones are raging as well, and my temper is short so I can only imagine!! Wshew, you've got a lot on your plate.
Patience, patience, patience. But consistency.
Time out and finding the right "button" to push with my little man was our key. For me it was taking a toy away for 24 hours & putting it in the garage on a shelf where he could see it but couldn't get to it if he failed to listen to me. No matter how he plead or said he was sorry, he COULD NOT have it back until the next "sunny day". Slowly he learned that he had better listen - Mommy meant business.
Also (and this only took once) I put him in time out once when Grammy was in town and we had a Dancey-Dance party (like on Yo-Gabba-Gabba) WITHOUT him!!! Oh-the HORROR! We danced all over the living room like maniacs & he had to sit there & watch. Of course he wailed at the top of his lungs & my poor mother thought I was torturing him, but it worked. (And secretly behind my back my mom had a dance party with him upstairs later...which I found out about afterwards!)
For me, it was finding his "buttons" and honing in on them. God knows, he has found enough of mine!!
Also, I limited the amount of rules we have in place so he's not overwhelmed by hearing NO all of the time.
We have oh, just a handful of MAJOR rules that'll land you in time out -
No kicking, hitting, spitting & saying NO to an adult in a disrespectful way.
That way he knows if he offends one of those rules he gets an automatic time out - he goes straight to the stairs no questions asked.
To lose a toy he gets warnings first:
First I say "Time to pick up your toys before bed".... "Look at me - time to pick up".... "Last warning, time to pick up or you're going to lose one of the toys" It's at THIS point that one of the toys goes to the garage shelf. And yes, there's ususally a full blown tantrum that follows. And daddy usually TRIES to rescue the toy because honestly, it's easier to appease the child than teach a lesson - especially at bedtime!
Consistency. It's hard, epsecially being pregnant.
It's so much easier to give in.
But in the long run, it gets easier to NOT give in.
And when they turn 4 they suddenly turn into little angels who want to love you and kiss you and tell you how much they adore you. It's amazing.
Good luck with the baby.
And the big baby too!
