Hello ! I need some advice

I just had baby little over 36 week and she’s only 4lbs 7 oz .

She’s pass all the test at the hospital doesn’t

need to go to nicu.

We’re home but she is barely eat , doctor said have to wake her up feed her every two hours .

I’m so worried about her what can I do make to make her eat more and gain weight I don’t want her to be in nicu. Please anything is help , she’s my first baby 😔
