Me, my husband and my 7 month old daughter just had a trip back to Hong Kong and came back last Sunday. She has GERD (acid reflux) since 2 months old but since she is taking a new med (Prevacid), she's doing better and not vomitting that much. But ever since last sunday night we arrived back in Canada, she could no longer sleep well. She's a GREAT sleeper since 1.5 month, But this week is a nightmare for us. She usually sleeps only for 4 hours, then ended up crying out loud, whenever we put her back in bed after comforting, she'd get up crying every 20 -30 mins. We brought her to pediatrician on Thursday and she said my daughter had a sore throat, but there was no virus that she may catch on plane or in Hong Kong. She is totally refusing to eat formula/solid and water as well, what caused her to cry? Cold? Reflux? Jetlag? She's very tired i can tell, and her weight just dropped....Heardbreaking and worried to death. She is a happy and good baby who doesn't cry for no reason, and now she's tired all day long, but couldn't nap for long either, showing signs of separation anxiety, probaby it's coz of the cold or something else, I don't know. It's a long weekend here, so what should I do in the meantime? Just wanna know what was the sudden change???
