When I put my 9 week old down after her middle of the night feed she becomes super gassy. She has reflux so after she eats I hold her upright 20 to 30 minutes and pat her back. She usually burps once or twice but when I lay her down again she gets restless and seems uncomfortable. I pick her up pat her back and she burps again. This happens EVER HOUR until it's time to get up which means I don't usually go back to sleep after the feeding. Any suggestions or ideas? We already give gas drops before every feeding a she is EBF. Gripe water? Maybe a probiotic? She sleeps in a Rock N Play at her G.I. specialists suggestion so her head is already elevated.
