I've heard a lot about how your pet can tell when you're pregnant. Some people even swore their pets "knew" and started acting different before they knew they were pregnant themselves!
Though I can't say that for myself, our little furbaby is A LOT more cuddly and snuggly with me, when she is usually a Daddy's Girl and only wants me sooo much when she's not feeling well. I don't mind though, I was always jealous when she wanted DH more (even though she was MY dog!) I think by now she can probably HEAR baby's heartbeat?
Did your pet "know" you were pregnant?
