My daughter is 13 months and won't eat. She either throws it down on the floor or just won't open her mouth. Everybody comments how small she is and it's really stressing me out. Made her wheetabix this morning and she refused to open her mouth, threw her banana on the floor and threw a croissant down. She won't take milk in the day. I'm still breastfeeding throughout the night. It's so so stressful. My older two sons was the complete opposite and wouldn't stop eating. What am I doing wrong?
