My baby is 5.5 weeks and I was just wondering - lately he has been going 3-4 hours for feedings. I know breastfed babies are supposed to go 2-3 hours, but he sometimes (several times daily) makes it to 4 hours with no problem. Also, at night he has gone almost up to 5 hours before. Is this amount of time okay? He is wet and dirty every feeding, and has gained weight just fine (birth weight: 6.11, now over 10 pounds).
