Infant with diaper rash and poor sleep

Hello, I am a mother of 5. My youngest has several things going on and I feel theybare all related.

She is a poor sleeper. She won’t nap away from me, startles easily. She won’t let me put her down most times and only carrying, nursing will help. She is demanding . When she cries she will get red around her eyes, cheeks, and ears. She will rub her feet together and they will get red too. Her nose will run. She is a fair skinned and light eyes. Brown hair. “Pretty” baby as strangers say. She sweats profusely in the top front and sides of her head. She emits a sour smell. She is slender with bright curious eyes. Curious disposition. Cries angrily. She isn’t walking yet just crawling. She had cradle cap develop that had a yellowish tint around month two. She develops slowly after month two also. Around month 6 she developed a rash. It was pink and round on one side. Right sides . She also has a red anus. Over time it worsened getting redder and fiery. With little shiny markings. She often scratches her head when agitated. She use to scratch her legs and make them bleed when she was upset. When nursing she scratches me too. She just started a small amount of table food. Her bowel movements are yellow and pasty or thin. Sometimes green tinged. She is a ferocious nurser and frequent. Sometimes I think I hear the milk dropping in her belly. She has rumblings and some gas.

I recently gave Sulphur 3 times one pellet 30c potency. Over 3 days. Rash improved. Nettle rash appeared shortly on face then went away next morning. Sweating less and less smell. Previously over the last 4 months she didn’t act to Puls. Calc carb, Chamomilla, in 30c potency. I tried Silicea 30x and it seemed to help rash anytime. No remedies at same time. All separate.

Advice to continue case please?
