hi everyone .. I need ur advice .. My toddler 2y & 2mnths old refused to finish her meal n reduce her milk intake .. Usually she will eat 3/4 or finished her meal but now only 3-4 spoon ful n shes done . her milk intake from 150 mls .. Now she only drinks lesser than 120mls .. Shes still active .. No sign of severe dehydrated .. Im worried .. Is this normal phase for her age?
