pets acting weird

so anyone that is due soon have your pets been acting weird around you? I think my dog and cats know something is going to happen soon. All yesterday my dog was following me around wanting to lay near me. He has always been affectionate but not so much towards me. Also my 1 cat started to sleep up at my head again. she use to do it all the time and within the past month she was sleeping in our daughters bed. for the past 2 nights she has slept right on my pillow and now she is snuggled close to me on the couch. again something she hasn't done in a while. I think they know I'm getting close. only 6 more days until my due date.
