Sadie Robertson shares her 4-month-old daughter is battling RSV: 'One of the most heartbreaking things'

Robertson and her husband Christian Huff welcomed their daughter Honey in May

Sadie Robertson opened up about her 4-month-old daughter's struggle with RSV in an Instagram post shared Friday.

Robertson, 24, gave birth to Honey, her first child with husband Christian Huff, in May.

"We have been walking through this privately, but I want to give y’all a window in because I know so many around the world are going through this," Robertson wrote alongside a photo of herself and Honey laying in a hospital bed.

The "Duck Dynasty" star went on to reveal the struggle she's been going through as Honey battles RSV (Respiratory syncytial virus), which the Centers for Disease Control and Prevention defines as a common respiratory virus that usually causes mild, cold-like symptoms but can be dangerous for infants.

"The past few days have been very tough. Watching your child sick is one of the most heart breaking [sic] things," Robertson revealed. "Seeing her little struggle brings me to tears like I have never cried, but seeing her strength has given me smiles I have never smiled."

It’s not over yet, and that is sad, but we are believing for the days to come!"
