Kaytee. We have had similar times. Ours is due to reflux, and medication has made a massive difference. Worth getting her checked out if you think the screaming is a pain cry.

The only thing that works to calm miss P down, and that's never a guarantee either, is a bath. Sometimes on her own or sometimes with me, it's the only way i can stop her crying. Nothing else works, like you i try the carrier, the pram, a swing, every position you can imagine, all to no avail. Although we have much more success with her over my shoulder rather than lying down.
