Some babies do slow some toward the end. None of my term babies did... Just keep an eye on movement - make a note (even if it's mental) of frequency. You still want to be feeling good strong vigorous movements at intervals throughout the day/night. It's true you won't feel full body movements as much but kicks and prods you will - my last term vaginal birth I could feel Eva kicking all the way thru labour! All the way down. It was beautiul.
