Hi 👋😊 If your baby hasn't start to crawl yet, can you let her do the tummy time everyday for at least 5-10mins? Try to put some toys at her front as her target to reach during her tummy time. Don't be afraid if your baby's crying as crying help to develop her body to grow. You can let your baby cry up to 15mins max and pick her up and put her back to her place. Try to schedule her tummy time till she get used to it ya. At first it'll be a bit hard, but please do it consistently ya
