Starting the prenatals again basically couldn't be bad (: funny thing about babies in the womb is they will often take their rest while you're most active, and be active when you're resting. Sometimes it's reversed, too (: my baby has done this a couple of days as well. Normally he never moves during work hours, to the displeasure of my coworker. But today and yesterday he was rolling and flipping, stretching and I swear he did some yoga too while I was working and when I got home was completely still - which made my sister sad :p babies are funny (: if yours doesn't move for several days I'd consult your doctor, but don't worry otherwise!
we have the exact same due date, Oct. 24th, and our baby boy hasn't been as active today.. well, not as active as he was yesterday. I literally said to my fiancé yesterday, "there's NO way he has this much energy, he hasn't slept!!!"
now today, it seems as if he's sleeping.. all day! lol - he's only moved when I poked my belly a little.. and I've felt a couple deep kicks/rolls.. sort of near my bladder. he was probably just getting comfortable..
keep in mind they're doing a lot of growing over the next few weeks, and no.. I don't think stopping/starting the prenatals affects anything! (((:
