is it okay to wake up baby at night for breast feeding   

For the first few weeks, if you feed the child once before bed and then early in the morning, the child will be fed sufficient. A child can stay hungry for those 4 or 5 hours of night. If the child’s weight increases 20 to 25 grams per day and he urinates 5 to 7 times or more, it is understandable that the child isn’t hungry and his stomach is being filled properly. After a few weeks, it's okay to let your baby sleep for longer periods of time in the night. Setting a definite eat sleep pattern can help babies stay healthy. Gradually babies can get disciplined automatically through their internal body clock and daily metabolism.
