Advice on the daily struggle with DD

[IWokeUpLikeThis]

DD is 9mo. In the past couple of months everything has becoming a screaming tatntrum; changing her bum, getting her changed, putting in her high chair, putting her bib on, cleaning her up, putting in the car seat, putting in her pram, putting her down if she's not fully asleep meaning some nights I'm rocking her for over an hour. She is also still BF and biting me.
She screams and wriggles and bangs her head, the only time she doesn't wriggle and scream is if she's really tired. She now fully refuses to have a bib on, ripping it off and she sometimes spits her food out everywhere.
It makes everything such a struggle now, and I feel awful for just doing things to her like getting her changed as she screams so much.
Can someone give me some advice on how to make it less traumatic? I need to gain control and not let her rule everything

She sounds frustrated and a ball of misplaced energy. I bet she will improve when she can walk and then talk. But first, is she teething, have you had her checked by a GP for an ear infection? Or has she got food intolerances? If she's stopped having normal nappies, or developed skin problems, I assume you'd have noticed.

Gain control by letting her have the illusion of control.

Is she facing you or outwards to the world when she's in her chariot? She sounds impatient for stimulation and entertainment. Do you try a particular toy for when she's going out? (That can work when feeding, too). Bribing with a favourite item is probably better than bribing with snacks.

If she won't wear a bib ditch it. Strip off her top or plonk a t shirt on instead. Is she feeding herself or are you spooning food in? She might slurp it but she's probably wanting a degree of independence and ready to have a go herself.

When does DD nip you? If she's not biting at the start of a bf session, but towards the end, pay attention to when she slows down, and remove her from your breast right then. It doesn't mean that bf her is over forever.

What's her sleeping pattern like? Naps, bedtime? It could be over-tiredness. Try and make sure she gets as much fresh air as possible every day.

The bitey-fighty thing could just be a developmental phase but it is exhausting for you.

I'm sure others will have advice.

I think getting a health check is a good idea, just to check no physical cause.
If it is wanting more control she might like some finger foods, also you can load the spoon then let her hold it herself.
