My 5 month old occasionally has really BIG vomits. Sometimes they are out of the blue - she'll just throw up absolutely everything that could be in her tummy. Other times she'll get a little choked while nursing (usually it's because she's fallen asleep and isn't as actively swallowing and my milk let's down), gag and then everything will come up. Those times seem like they have a more obvious fix - unlatch her when she's so asleep she isn't actively swallowing (or try to keep her roused). But when she just randomly vomits, it's pretty upsetting. She doesn't have other reflux symptoms. I'm unsure of her current weight, but she was fine at her 4 month checkup. 50th percentile (up from 35th at 2 months). I kind of expected these large vomits to ease as she got a little older....?
