What time of day do you feed your ball? Some are really sensative to photoperiods, and may only take food closer to nightfall, or you can mimic that by shutting any blinds in your room, turning the light off, and possibly draping a towel over her tub while the prey item is in there. And when you say baby, can you give us a rough estimation of how old she is? If she's 4-5 months old and has had a few decent meals in her, she could just be letting her digestive system 'catch up'. Have you tried the paper bag method, or spraying the prey with a little bit of water? And are you feeding her in her enclosure or in another tub? Force feeding is an absolutely last resort, as it will cause even more stress to the ball then just not eating at all. I would personally take her to a vet before I would force feed, just to get her checked out and make sure that nothing else is wrong with her. Hope this helps some
