terrible twos early

Gone • Nope
My son is getting into his "terrible twos" early and oh my is it frustrating, he's so bad, just ornery all the time and really pushing boundaries also his tantrums are just the best. I'm 13 weeks pregnant, my morning sickness is sticking around and so is the severe exhaustion and that's not really helping my patience. I'm a stay at home mom also so I deal with his tantrums all day long...any suggestions on how to deal with the whole situation?
