Baby cries all night before sleeping

Hi,

I'm ftm and have baby who is 11 months old.

She doesn't like sleeping at all especially at night. She takes 2 nap s at day time and the duration mostly will be an hour or rarely 2 hours each.

She is sleeping at 2 am or 5 am and cos of this I'm feeling tired all day. In order to make her sleep I need to keep on rocking her.

Day time just for those 1 or 2 hours sleep I need to be near her all time as she will start to make sound and I have to talk something to get back her to sleep.

Even if I'm 10 seconds late to respond she never goes back to sleep.

I have asked my ped but he told all these are normal.

I have given her warm milk before night, dim the lights etc. She is feeling sleepy but she doesn't want.

Just need to know at what time babies go to sleep so I can rest for sometime

Edit

She again sleeps just for 3 hours. Yesterday night she slept after 12 am until 3 am and slapped me to wake up. She kept playing herself for more than 2 hours may be and slept again for an hour and got up. Whole day no naps and just she have started to sleep.
