Not yet roll over at 6m

hi mummy! I'd say to just go with the flow. You can intro more tummy time , with baby's favourite toy on her side to encourage her to roll over. my son was the same back when he was at 5 month+. didn't want to flip , roll over. didn't crawl. when the time came, he suddenly did all that by himself and wouldn't stop 🤣 now he's 15 month and he's reached milestones. take it slow mummy . 😊 if it is any concern , you can always consult a pd , but as long as baby is well, I'd say just keep up with her. she probably will start rolling when she feels comfortable or might even skip doing so.
