any other moms?

I have a 18month old son and he has been acting up lately, he has been throwing tantrums I've never seen him throw before he just wants mommy no more daddy and is just no himself. I am currently 34 weeks pregnant. My first son was born at this time. Anyway my mom thinks that it's because he knows his time is coming up so he's trying to get as much attention as he can from me. Has anyone else had a similar experience?
