M.N.
Only make her choose between 2 things. If you are just asking her what she wants with no options that is a HUGE question (maybe not to an adult but to a 5 year old it is).
Would you like a sandwich for lunch or some chicken? Would you like this book or that book? This shirt or that shirt. This way the choice is not so big and intimidating.
Also, I believe this is pretty normal. My daughter would get very overwhelmed if she had too many choices.
Once she gets comfortable with just 2 options then you can always slowly increase it if you want.
Good luck!! and YES the time goes by VERY fast. My baby is now 10 years old and I can't believe it.
