Gel mix Thickener

Esmeralda

Went to my baby’s appt this morning. She has been having lots of spit up , and hard time pooping but her doctor said it’s normal 🤷🏼‍♀️. Her doctor switched her to Similac Sensitive , ( was on similac advance )

‼️ He told me to add gel mix thickener to her bottle when feeding ‼️

Has anyone used it or know what it does ?

And anyone use similac sensitive ? How do y’all like it ?
