This Breastfeeding mom is confused please help❗️❗️❗️

Desiree

Hey ladies...So I took my baby to a doctors appointment because he had a rash and I wanted to get it checked out.He got weighed and he lost a pound.😳 He is 5 months and we are exclusively breastfeeding.I know he is content when I feed him because he either unlatches himself or falls asleep. I had to try so hard from crying at the doctors office because it made me feel like lm failing my baby.He looks like he is getting bigger to me and his dad.Even his doctor said he looks bigger.She told me not to worry about just yet and she wants to see him in 2 weeks to check his weight to see if he’s gained anything.I really dont know what to do.Has anyone ever experience this?
