My little guy has always fed every two hours from birth and last week he was sneaking in one three hour stint usually for his first sleep after we go down for the night then he will still wake every two, to my knowledge two to three hours was normal. He will be six weeks old Tuesday we spent yesterday out and about with grandma all day and he slept 4 hours straight for his first sleep after being put down for the night..is that normal ?? If he's sleeping longer periods of time do I let him sleep ?? do they tend to go longer and longer?? how soon does a breast fed baby sleep through the night? He woke up happy then after speaking to him for a second and a nappy change he got upset because he was ready to nurse and refuel.
