5 week old eating 1-2oz

Emma

My daughter’s pediatrician wants her to eat 3oz every 3-4 hours but she’s still only eating 1-2oz every 1-4 hours. I feel like I’ve tried everything to get her to eat more but it isn’t working🙁 She’s formula fed and on nutramigen for milk protein allergy. She also turns 6 weeks on Wednesday 😩

Does anyone have some recommendations on how to get her to eat more less frequently?
