hi I have a cross beak too! mine is almost 51/2 months old now. with a little help from me she leads a happy normal life. first off the crossing of the beak gets worse as they get older. so to help you MUST start trimming the beak around two months of age or before. I trim BOTH upper and lower beak to prevent over growth very important. use extreme caution when trimming the lower portion of the beak the tonque is there. I rotate about every month upper than lower. second feed her separately if she is like mine she gets pecked on so at least give her a separate plate.third mash her food you can use regular chick feed and just add water then mash it up.its much easier to eat that way. fourth add some vitamins to her mash. this will help her gain weight and stay healthy. these are the steps I take to keep mine healthy. there was a time I thought she could just eat the feed without mashing it but she became terribly thin. so now after feeding mash she has put on weight and doing much better. the once a month trimming of the beak is VERY important as it can grow out of control very quickly. I'd start trimming her at about two months old or maybe sooner. do not worry if it might bleed because sometimes it happens accidentally. don't worry your bird can lead a happy healthy life with your help! just don't breed her as its a genetic defect.like I mentioned it WILL get worse with age so don't be surprised. other birds might pick on her keep some Peck no more on her back and it will keep the others away and from pecking her.I hope this helps and wish you the best. any questions I'm happy to help just pm me. good luck
