I agree with the above. Thhey are cute but she might not want to be "cute" forever
I think both are good little-girl names. I would possibly suggest giving a more formal or grown-up middle name, in case little Lexee or Taytum wants to be president of a bank or a judge or President when she grows up. She might want to use her more formal name for a more formal career.
Both r super cute! But I like taytum a lil more lol (:
