i know what you are going through... my child went though something similar... it reached a climax where i had not slept in 4 days and had not even eaten during that time... i was refered to a mother-craft centre and i can not say enough about the benifits of our stay there...it sounds silly but babies do not know how to go to sleep,i was taught that teaching baby to sleep also its important to give them a routine... i will tell you my routine and i hope you can make it suit you by changing it in a useful way.my child was the same age as your baby so i am hoping this will help to suit you sweet child.

6am- baby wakes and is fed, bathed and some play time with momma. then baby should have a nap.
10am- again baby is awake and fed, play time and should be back in bed.
2pm-same as before
10pm- more of the same....

people often dont recognise the symptoms of a tired baby... baby will begin clenching fists, grimacing and waving arms in the air... babies sometimes disply irritability. do not rock your baby to sleep or feed them untill they sleep as it does not teach them to learn to sleep on their own. they need to learn to settle themselves for their own benifit.
make sure baby's room is comfortable and tuck baby in... pat baby for 3 min on the back while making soothing sounds like shush-shhhh (its impotant you do not speak to baby) then leave the room. if baby wakes wait around 2-5 mins before going back and repeating the patting and soothing sounds. it will take sometime for baby to learn, about a week. please be diligent and strong while you are teaching baby to sleep, but i promise you that if you stick to this then your baby will soon be so easy that all you need do is kiss your precious child and tuck him and and he shall sleep. good luck with everything you are indeed blessed to be a mother.

Hi Kate
My baby is 6 months old and I just logged on to this website wondering if i wud find anything on how to make her sleep thru the night. Ur routine seems very sensible, going to try it out.

Thanks Rasmi pavneet replied. I think the topic is really nice and worth to focus. Thanks..
Would like to ask one thing...
my daughter is 2 years old and is very naughty. It takes one to two hours to make her sleep at night. I don't know how to tackle a child of this age while sleeping especially at nights....
