My one year old who still breastfeeding is killing me. Refusing foods, liquids and really feeling he’s only trying to rely on me for food source... any suggestions, support or ideas. He doesn’t sleep through the night. I’m feeding him meals and he usually throwing everything to the floor! Im going insane! I feel like it’s my fault he’s restless and crying.
