S.H.
I don't think this is night-terrors. But you can read about it online.
How about, since you said she wakes easily... when she does wake, just wait. Wait and see if she will settle herself down by herself, first. THEN, if she does not, then you need to go in and try something.
Or try white-noise. When my son naps, we put on a fan on low... and he likes this. It mutes out the other household noises while he naps. And he has a lovey that he loves sleeping with.
Many babies/kids wake sporadically during the night.. but it does not necessarily mean, you need to go and pick them up right away. Many times, they will go back to sleep.
ALSO, make sure she is taking naps during the day. An "over-tired" baby/child will NOT sleep well at night. Over-tiredness actually makes a child unable to sleep well at night, AND they wake more.
ALSO, before bed, make sure she winds-down first. And keep things calm/quiet etc. Not active playing before bed, as some kids do. Even an hour BEFORE bed, just calm things down first.
Or maybe she is teething.
But as you said, every child is different with sleep, ability. My daughter, since birth, was noise sensitive and a light-sleeper and very alert even during sleep. Even a flushing toilet would wake her. She was just more sensory sensitive. So, we went according to her and her rhythms. My son on the other hand, was so much simpler to put to sleep. He was routine oriented, and did well with a sleep schedule. Whereas my daughter did not... she had different needs. BUT By the time BOTH my kids were about 2 years old, they were sleeping through the night. As many kids do. But I never let them cry it out. It was a natural progression, and per their sleep maturity ability.
There is no single "cure" for sleep deviations, since all kids are different.
Or, make sure she gets a good feeding before bed. Since during growth-spurts, they tend to wake more.
All the best,
Susan
