Im desperate...advice please 😔

anon

My daughter is 13 months and recently acting defiant over everything. Eating, playing , changing nappies etc. She makes this screaching sound that does my head in. I tell her stop and try and re direct her to something else so she stops but sometimes nothing i do will help. I cant help but feel like a garbage mother because some days i feel like all i ever do is spend the entire day telling her off which makes me feel so guilty i end up crying after she falls asleep. Please tell me it gets easier or please give me some hope or advice. I dont want to smack her or raise my voice. ..how can i correcrly discipline or stop her from doing something naughty? Im desperate 😪
