Hungry baby tired momma.

Trisha
My son is 2 weeks 2 days. When I pump I get anywhere between 5-7 oz from each side so I know I make enough milk for my son. He latches wonderfully and I let him eat till he spits out my nipple, he has been having plenty of wet and messy diapers but he is starting to act hungry every hour and a half or so instead of every 3-4 hours like before. I'm tempted to start using bottles and pump instead of breastfeeding so i know exactly how much he is eating each time. What say you?
