Toddler not eating well. Worried 😔

RJ

Hi ladies. My girl is 19 months old. She used to eat proper breakfast, lunch, dinner n snack. Since 10 days she is not eating well. Infact not eating meals at all. She is refusing everything. She is having light snack like teethers, but that doesn't fill her stomach. She is drinking milk only. Iam giving milk atleast to fill her stomach. I am so worried should i call her pediatrician. Pls do respond. Thanks
