My baby girl had her 4 month well check today. Her height and head measurements stayed at the same percentile as her 2-month but her weight dropped from 46% to 22%. Doctor ordered some stool tests. I’m pretty worried (and also have a history of anxiety, so this kind of stuff is always difficult for me). Has anyone had experience with this kind of drop? She’s still gaining, just not as quickly as she should be. Please give me any experience/advice or info you have. She’s exclusively breastfed and my supply seems great.
