Do kids know if your expecting ?

AlyCat😼 • expecting baby #2

My son has been super clingy to me and my husband , like everyday he wants to call his dad to come home from work because he needs him home and our son keeps telling everyone we’re having a baby or he’s ready for a baby

I took a pregnancy test earlier today and it was a faint line we’ve been ttc conceive baby #2 but we’ve haven’t told our 4 year old anything

Do y’all think kids know or feel things just like how sometimes animals get around pregnant women?
