In need of breast milk for my newborn

Description

Hello!! I’m needing to purchase breast milk for my newborn son DJ. He was born early at 36 weeks. DJ was born 6-18-17. I have been trying to breast feed and pump this whole time. I just don’t produce enough for him right now. I want him to get the best nurishment right now for his age. I have been substituting with the formula but it seems to give him a belly ache. If someone could help us out WE especially DJ will greatly appreciate it!! He is currently taking 2oz-3oz a feeding.
