Baby movement

Help. My girlfriend is currently 25+3 weeks pregnant and we’ve felt out baby daughter move a lot but the last 3 days shes hardly moved at all. She’s really worried bout her movement as my girlfriend and I are both worriers as we had a miscarriage before we got pregnant with our daughter. We’ve tried cold drinks, shaking her bump, shining a light but still nothing. I do talk to our daughter a lot. As I’m writing this she has kicked once and that was it. Any advice welcome thank you.
