I'm pretty sure they can. On pregnant with my third now. But with my second pregnancy my daughter some how new and was really attached to me. Now my youngest is really attached.
I honestly think they do feel it. My 2 year old has been extra dramatic lately except she doesnt want me to hold her she runs more towards her dad. We also just found out almost two weeks ago
I agree right when we found out our toddler started saying don't leave me momma don't leave me. When I go to work, the store, the bathroom. She usually loves staying with her dad but has to be with me constantly.
After reading your post & other other responses I definitely think they do. My 2yr old daughter kept telling me over & over waaaayyyy before I found out that my stomach was gonna get big & I overlooked her. She wanted to sleep right up under me & started kissing & rubbing my face more than usual. So after feeling sick I did find out I was PREGNANT!! Strangely...I never told my 2yr old & she kept asking for a "pink sister baby"...lol! One day she said "Ma I want a sister baby not a boy baby!" Sure enough I was very surprised I'm having a BOY!! Somehow my 2yr old knew or felt something was goin on.
Yes, I believe they can. My son was saying baby and rubbing my belly before I even knew I was pregnant
