Yes my 2 year old got really rebellious and acting up as soon as i found out i was pregnant
I started to notice my son started throwing bad tantrums.. i later told my mom how out of no where even if i smiled at him he would throw a tantrum or he'd just want me to carry him all day the first thing she told me was "you're pregnant" lol sure enough i took a two test went to see my doctor she said i was already about 12weeks.
Yea they can. My daughter wanted more of my attention when i was pregnant.
Have you had your baby yet? If so, did he get better when baby got here?
