Decreased Appetite

Hi,

My little one suddenly has decided that she’s gonna have a decreased appetite. She usually drinks 32 ounces of formula and her meals with water. However for the last few days she’s gone to 24-30 but still eating her meals and acting the same as usual. 9 month growth spurt and teething are all I can think it could be. Has anyone else experienced this? She’s having a wellness appointment just after Christmas which I will bring up to her pediatrician. But, I just wanted to know if anyone else had this issue.

Thank you!
