Decreased eating in a 7 week old

My 7-week old baby has been eating less and less these days. She was diagnosed with reflux at 3 weeks and a milk protein allergy at 4 1/2 weeks. She was started on Neocate and I started a total elimination diet. We re-challenged her to breastmilk (one bottle) and she did not do well, so she is back on Neocate. I've been trending her intake since we started the formula and her daily intake went from 18-21 ounces at 5 weeks to 22-24 ounces at 6 weeks to 15-18 ounces at 7 weeks. She's fussy at the bottle and refuses to eat any more after burping. Of note, she's on Prevacid 5mg BID and Enulose 1tsp BID.

Thanks!

The position of feeding is important and should be in about a sitting up position. Never lay the baby on their back right after eating or ½ hour after eating because the acid from the stomach goes into the esophagus and causes pain. Raise the head of their crib to a 45-degree angle too so they is not flat on their back. Feeding them 5-6 times day help. Feeding that way keeps the stomach acid constant, which helps the reflux, they grow, and weight increases at a steady pace. Hope this helps.
