Baby does ever sleep

I already posted this the other day but only had one reply because i posted it in the middle of the night lol. So copy and pasting hoping for more answers 😂

I may be wrong but aren't 1 year olds supposed to have around 14 hours sleep in 24 hours? My daughter 100% doesnt get enough sleep, she just turned 1 and she has one nap per day which is 20 minutes long. She is then still awake at 9:30pm and usually falls asleep between 9:30-10pm and even thats a struggle to get her to sleep. Then she wakes up about 3 or 4 times during the night and at least one of those times she will be wide awake for about an hour. Then she wakes up for the day at 7am. So she probably gets 7 or 8 hours sleep in 24 hours instead of 14 hours? Obviously ive spoken to her health visitor and doctor and no one wants to help me, they say I have to be patient with her and just trial and error different things. Ive tried everything, surely this amount of sleep cannot be good for her? (or me 😴)
