6 mth old spitting up depite meds?
I have a 6 month old little girl. She was born 8 lbs 10 oz. At her 4 month check up she was only 10 lbs 6 oz and the pedi switched her to Similac Alimentum and changed her from Zantac to Prevacid. She's now up to 13 lbs 5 oz but it seems that we have hit a wall again at 13 pounds. Her Prevacid seem slike it's not working anymore, as she can spit up 4 hours after her last meal, regardless if it's straight formula (thickened with cereal) or food. We go to her 6 month check up in a few hours. Is there some kind of test that I can request them run to see if it is just acid reflux, or if there is something more going on?
