My baby is nearly 6 months she is not drinking her milk properly. She is getting really frustrated and tense. She will scream and literally tighten/stiffening up and I don't know why!

She drinkes her morning milk fine, but after that first one it goes downhill.

The teets are size 2, which is suitable for her age, I don't know what to do the childrens doctor said barely anything.. just to book me a appointment for one weeks time! Useless.

She has had diarrhoea also, and looks like she has ringworm on her chest?? I'm calling 111 tomorrow morning as she's sleeping now.

Any advice?
