My newborn sleeps continuously up to 4 hrs with out any feed, should I wake him up in between for feeds?

It might seem like a terrible thing to do, you may need to wake up your newborn for feed if he is sleeping for more than four hours. This is because: 1. Most newborns lose weight in the first few days after birth and it is important for him to feed frequently till he does not regain that weight and reach his next milestone weight -- especially if he is sleeping more than four hours at a stretch. 2. Crying is a late sign of hunger. The baby may actually sleep through his hunger and you may miss signs like him sucking his fists or smacking his lips. If he sleeps through his feed time, it could lead to crying. 3. Frequent feedings can increase breastmilk supply.
