Almost 1 month

Rebecca
My daughter will be one month on Sunday the 17th, right now she is eating 3oz every 2-3 hours at night time, but during the day is very diff, she naps at her normal times but then wakes up screaming that she's hungry..so my husband and I feed her the 3oz, but then she's still hungry. I'm afraid to make her 4oz to were she throws it all up. If I made her 4 should I do it more during the day/afternoon to keep an eye on her. I'm not sure what to do!!
