Super slow eater

Hi! Our 12 week old has been a slow eater her whole life. Regardless of breastfeeding, Nutramigen, and now Neocate, she takes so long to finish a feed.

She drinks 4-5 ounces 5x a day. For her night feed she drinks 5 ounces within 20-30 min then goes right back to sleep. During the day however it takes 45-60 minutes. I do all the recommended tricks to try to keep her awake but she is usually snoring by 3 oz and it’s a battle to get her to finish at least 4 oz.

Any tips from more experienced moms?

We use lansinoh s, she won’t even drink from the m size nipple, it just puts her to sleep.

My husband just went to target to buy Dr. Brown, so we’ll see if that helps…
