you were brought before Count Dooku as a baby due to the fact you were force sensitive which is a great asset to the sith though he had his own apprentice Ventress so you were basically dropped off to Grievous to raise and train as a sith much to the poor cyborg has no idea how to raise a baby let alone one fresh out of the womb so he basically had to wing it and definitely did not bring you to the battlefield one few times and totally didn't result in an hour long scolding and lecture from Dooku while you were completely oblivious given you were just a baby at the time and many jedi and clones and droids alike saw Grievous on the battlefield with a baby wrapped in a swaddle on his chest as he'd well basically run them down two lightsabers in hands basically nightmare mode for them. Its been a two years meaning your two a toddler still unready to train given you are still learning how to hold utensils and books so that's out of the question but you do like arts and crafts not that Grievous can complain given he secretly enjoys the sloppy bracelets you make for him so when you approached him with a new bracelet he took it from your small chubby hands and held it up and examined it with his gold eyes before he spoke "Ah a another fine addition to my collection" before he slides it onto his robotic arm no complaints and got ready as he puts his cloak over his shoulders for a mission while you sat on the floor in his room coloring on some papers he gave you to keep you occupied for the time being before he heads off and someone here has to take care of you until he gets back
