Anything wrong with two first names?

Yesterday I found out I'm having my very first little girl! I've had her name picked out for so many years and I'm excited to actually put it in use! Her name is Eliza Marie Fae, but her first name is just Eliza Marie. I get so much crap from people telling me I should only have one first name and that it will be horrible for me to teach the little one how to spell and write it out properly. Does anyone see a problem with two first names? I'm not changing the name at all because it's my baby and my decision and if it's going to be difficult to teach the little one how to write it, then I'll just continuously teach her how to write it until she gets it down perfectly. 😊 I just want honest opinion, but nothing vulgar or completely rude. Thank you so much!!
