Hi all I’m really struggling with my DDs tantrums....she is so incredibly head strong and defiant that I can’t actually manage her anymore. I’ve tried everything - acknowledging her feelings, setting boundaries, giving her control and options over certain things, providing 5 min warnings Etc but every little thing she pushes back on and then has the mother of all tantrums. It’s been particularly heightened these last few days (there has been no change to her routine, life surroundings etc, so I can’t pinpoint why) She Tried to run into the road Today and because I grabbed her and tried to explain she needs to hold my hand to cross the road she had a 20 min tantrum on a pavement 
I’m currently being treated for PND (taking me a very long time to seek help) but I find this behaviour so triggering. Shes always been incredibly active and hyper - I wouldn’t be surprised if she’s adiagnosed with ADHD When she’s older. She’s extremely demanding - the moment she gets hungry she will literally kick and scream (yes I have a meal and feeding schedule but even a few mins before dinner is ready she will literally kick and scream and hit) it’s like her feelings have always been high on the surface and she can’t control them. Her language is pretty standard for her age and I’m trying so so hard to tune into her and provide her with the language and signing she needs - but it’s like her emotions just take over. She’s now at that age where terrible 2s are creeping in and I’m finding myself getting more and more isolated as I’m so mortified every time we go out and she’s lying on the floor screaming her head off because I won’t allow her to do things that could harm her. Any advice? Please? I’m a single mum and struggling terribly
