Is her dad involve? in the discipline? I find my toddler is more likely to listen to my husband as he is more firm with her.
How did she do with her health visitor 2 year old checks, did you have any concerns there? Has she been in a preschool? Do you think it’s purely behaviour or some Lack of understanding and communication need?
Gentle parenting with some sprinkles of firm parenting. Also being consistent. How You discipline at home should emulate how you discipline in public so she doesn't feel she can get away with certain behaviors while outside. My son who just turned two displayed similar behaviors but I really worked hard on trying to nip it. It's not 100% but it's gradually getting better. I ensure that whomever is watching him is also intune with how I choose to discipline him. Having patience too is another big one, and not feeling overly defeated. Just keep working on trying to talk to her to gain understanding on her level, it's honestly on a child and parent basis.
For me when he starts acting up, I speak to him in a calm manner and if he doesn't listen I Raise it up a some notches, but not overly, letting him see my face is not in acceptance and being consistent with him in that moment till he stops. With the crying I always give him his moment then he has to wrap it up. I tell him to find peace in his moment, calm down and move forward. Shhhhhing him down, wiping his tears, calming his energy down, it helps. Like I said it takes time. Finding ways to alter and improve the behaviors. Also give yourself Grace because parenting is no walk in the park. As for her dad, it gets a bit tricky with discipline too if it only on the weekends. You don't want to be in a situation where she only listens to her dad and is only good on weekends. But definitely connect with him to get on the same page with discipline. It won't happen overnight but do what you can with each moment and day! ❤️
Sorry you’re going through this. When she misbehaves, how do you react, are there any consequences for her behaviour?
