Congrats to you on your new baby. I do believe you saved an angelic soul!
In regard to potty training - yes, they can be difficult because their bladders are so small and the muscles are not developed. Be consistent if you are going "outside." When you go out keep telling her "go potty" or "go poopy" or (we use) "Get busy!" Reinforce this each time and when she does go give her lots of praise and some treats. We also use the "bell" method. When ours need to go outside they just ring the bell (we have a ringer on the floor for them).
In regard to the ears. Right now the calcium in her body is being used for her adult teeth. One of the best things to do (besides keep the ear-hair trimmed) as to fold the ear together (liek you are closing it) and tape it.
I'm not sure how picky you are on ears but I've got two with ears that can pick up satellite signals and one that has floppy ears. Honestly, it adds to her personality.
Welcome to YT! I know you will get alot of input.
