I had this happen to me a few days ago and I started to panic because while I could still feel kicks, they were a fraction of the intensity and not in their normal pattern. Baba clearly likes to keep me on my toes because I was about to ring the hospital that night but baba then shifted back and kicks felt 'normal' (for me) again. If you feel worried about it, it's worth calling your midwife especially if you are concerned for a long period of time/not feeling kicks but try not to worry , there's every chance baby can shift back again. They just like to keep us on our toes!
