Hello,
My baby is 9 months old, she normaly did sleep good at night. But suddenly she wake up and starts crying for 1 hour or longer, then sleep a little bit and start again. We are so tired...

Before I give her a soother and she went to sleep. She maybe woke up 3 or 4 times, this was when she was like 7 month, then she started sleeping trough the night, from 7 til 7.30. This when she was almost 8 months.
Then she started waking up early and we bought new shutter for our windows so it is really dark, she started sleeping better, from 7 till 7.
But now she suddenly starts crying in night, i give her a soother but she still cries. I don't now what to do. If i pick her up she is quiet, also if we bring her to our room, but if we put her back she start crying aging. She never did this before. She always goes to sleep by her self again.
She doesn't sleep much in the day, only 45 minutes in the morning and 45 in the afternoon, sometimes she does 1,5 hour in the afternoon, i did make her awake time longer and i put her now for 2 naps, at 10.00am and at 2,30 pm. Im still trying to get better naps. I its going better the last week.
So i don't think she sleep too much. I hope somebody can help me. She is never been a good sleeper but only in the daytime. I the night she always slept good, in the beginning she ofcourse got her feed every 3 hours and then she slept.
Please, help

I forgot to say that we always have a sleep routine, we say good night to her stuffed animals read a book and give her her milk then she goes to sleep by 7,15 for the night. The last six week she also eats less then before, i don't now why.
